Quickktime export to fit dvd media disc

Hi.. I have CS3.. I keep getting asked for my films to be exported in quicktime lossless media file to be sent to festivals for screenings.. my films are only 3-5 minutes long.. but when I export as quicktime they come in at 8gig.. can someone tell me how to export quicktime a 4 minute film..HD 720p etc that can fit a DVD.. this has been puzzling me for ages..thanks

Now, beyond going with a higher capacity disc, and having one media file per disc, you have only one choice, that I see - cut the bit-rate way down. Test the output of this, as you might not be pleased with the resulting quality.
As you are talking about a fixed CODEC (specified) and Frame Size (determined by you), and a fixed Duration (determined by you), then bit-rate, or larger discs are all that I see.
Programs, like DVDShrink will likely not be of much use, as you have data files on a DVD-Data. Those are designed to work with the MPEG-2 of DVD-Video discs. Still, you might want to look into them, as perhaps one WILL work acceptably with your AV files (data).
Even using archiving programs, like 7z or ZIP, will not squeeze much, if anything out of the files, and might actually increase the sizes. Also, the recipient would first need to Extract these to play them.
Good luck,
Hunt

    MAC MINI MATSHITA DVD-R UJ-845C
    Mac mini 1.42GHz PowerPC G4 | 512 MB DDR SDRAM
    Tiger OS X 10.4.3
    Finder Burn - single folder containing many sub-folders totaling about 800Mbytes and approx. 4000 files.
    Burn Speed Options : 4x(faster) : 2x : 1x(more reliable) - actual Finder media disc burn dialogue descriptions
    [default selection is 4x(faster) ]
    We choose 1x(more reliable) ..
    Observations include .. no 8x speed media disc burn available from our little Mac mini Matshita DVD-R UJ-845C burner .. and .. as this is a DVD R .. we have time .. but no going back once burned .. and we want maximum systems compatibility .. you, dear reader, already know the drama we have previously experienced with Finder burns and older Apple iMac DV SE machine DVD drive (media disc burned) read compatibilities.
    The total burn was a lengthy delay before the entire routine was completed including automatic verification.
    OUTCOME
    This disc did not verify correctly and is unreliable. Because this disc is unreliable, discard it and try again using a new, blank disc. (Error code ) 0x80020063
    Total disc burned is almost 800Mbytes and about 4000 files.
    Verification was not an available option for the burn .. a Finder burn .. meaning verification was apparently automatically included as an unseen 'yes' option at media disc burn execution time.
    Examining the resulting Apple DVD R media disc burned .. we discover that things are good .. biggest single files (.dmg's at about 100Mbytes expanding to 350Mbytes - e.g. OS X 10.4.3 update) are able to be copied from the burned Apple DVD R media disc back to the Mac mini hard disk again and verify 100% when opened for installation. Encouraging. Better than anything previously experienced.
    iMac DV SE [ DVD MATSHITADVD-ROM SR-8184 ]
    Into the Apple iMac ancient (500 MHz PowerPC G3 operating OS X 10.4.3 Tiger | 640MB SDRAM) and we are greeted with goodness .. same accessibility as the originating Mac mini machine .. satisfying.
    And yes the 'problem' of multi-session burns is yet to come on the ancient iMac and if the response is any good as now .. it may not be a problem worthy of mention. At 800 Mbytes burn and 4.7 Gbytes capacity .. one could loosely forecast up to another 5 media disc burn sessions before the DVD R is full and complete.
    XP MACHINE
    And now into the PC machine for an XP looksee and again .. more goodness. Cross compatible files are fully accessible (an entire - own - website burned). Large files copy 100%. Better than before.
    Two thumbs up for this disk and burn.
    Verification failure remains a current mystery. Anyone ?
    It is easy to figure how one may doubt one's media burning hardware is any good by now .. but the gathering volume of supporting entries at the relevant media burning and error message forums reveals that hardware is unlikely to be (entirely) at fault .. rather something else .. say firmware ?
    Apple Media DVD R discs are manufactured in Japan (stated on the disc) and the quality difference and price premium are consistent with what others have written of the place of manufacture and the Apple media disc as well. Mostly positive.
    Still .. we should like to have access to dependable RW discs from Apple too .. for reliable re-useability.
    As for the subject of burn speed ...
    Many forum readers are well aware of an ongoing and gradually escalating matter between Apple and this gentleman http://www.crc.id.au/page/2/ .. we have curiously followed the unfolding events to observe the outcome of the burn speed specification variation. As you know .. our Mac mini is rated at maximum DVD media disc burn 4x and fitted with a MATSHITA DVD-R UJ-845C which is a later edition than Mr H's UJ-835 .. however .. we are more curious to observe whether the final outcome will satisfy Mr H or not. Burn speed, primarily, and quality of burn, secondarily, on selected media by Mr H. Once the outcome is known and to Mr H's satisfaction .. then we may enquire about his satisfaction with burn quality at the chosen burn speed(s) by Mr H.
    Here is an offline forum communication that we shared with another Mac mini user about disc media burn speed. As you may read .. he is entirely dissatisfied with the Mac mini media burn speed and isn't too keen on using the Apple disc burn media either ...
    So...Have you found any dvd-r or +r media that burns reliably on the mini? (non apple media please).
    I am completely disgusted with my new mini's pathetic superdrive that I paid way too much for.
    I have purchased new & built from new parts several PC's that burn DVD after DVD on a wide variety of media reliably.

    We have thought the SuperDrive matter you have referred to in your post was of no concern to us .. but now you have us thinking again .. although model numbers differ .. (ours is a later numerical reference) the concerns appear to be similar .. or largely about performance .. we shall also refer to this domain in our planned next post. Yes, we are aware of the matter .. from another forum .. but shall now supply the link for others to weigh and hopefully dish out their two cents worth .. where a consensus could mean we are also a part of this particular action. An ideal consensus would be firmware is unsuitable .. requires immediate update .. and in particular the quality of burn is consensually unacceptable .. action could follow.
    We have progressed no further with burning experimentations .. and will be using Apple media before progressing with our findings reporting. For now, we are unable to add to your ease of mind .. frankly .. unless the burning media is made in Japan .. we doubt any burn verification success is to be had. And we cannot find any burning media made in Japan in our locale. Where is the Apple media made?
    We have come to appreciate the SuperDrive is all about the firmware .. but have no new firmware to apply .. in fact .. our research to date shows that we have been unable to find the Matshita SuperDrive at all online and cannot confirm specifications .. neither could we locate the specifications at www.apple.com.au .. which is just plain odd.
    A third look has provided ... from www.apple.com/macmini/specs.html ..
    Storage
    * One of the following optical drives:
    o Slot-loading Combo drive (DVD-ROM/CD-RW): reads DVDs at up to 8x speed, writes CD-R discs at up to 24x speed, writes CD-RW discs at up to 16x speed, reads CDs at up to 24x speed
    o Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed
    Where were you able to establish your SuperDrive (burning) specifications ?
    Writer's note : .. some things change .. and so have the Apple Mac mini SuperDrive burner specs changed .. since recording those detailed above. In fact .. they read like they maybe should have all along .. 8x DVD R media burn speed. DL is a bonus. Can anyone tell us what the drive designation is please ?
    CRC says: ".. This limits burn speed to 4x for Mac Minis and 8x for Powerbooks.".
    While speed matters .. and it does .. you appear to have exactly the same media disc burning problems that we are experiencing .. failed verification(s) .. and for us .. in short .. complete DVD-R media disc burned rejection from the Apple OS X.
    Do we .. in actual fact .. have two separate operating challenges here .. speed of burn and quality of burn .. any burn ? Speed was not our first priority .. quality is .. now we figure that at any speed the burn quality is anywhere from dubious to coaster.
    CRC says: ".. The UJ-835 that Apple use is firmware limited to suit various bits of hardware that they want to put together. The burner in the Mac Mini is the exact same model as the one in the PowerBooks. Apple load a 4x firmware on the Mac Mini, and an 8x firmware on the PowerBook drives.
    My bet is that this is for marketting reasons only. ".

    My parents have a mini and my has one of the PowerBooks. Confirmed the drives are Matsushita UJ-835. They have never had an issue burning DVDs. Confirmed it by burning DVDs last night on the wife’s 12″ PowerBook.
    As far as updating the Firmware in your optical drives, no, you do not have to remove them from the machines to update their firmware. I’ve updated the firmware on my optical drives (for Region Free and/or speed gains) via the GUI in Mac OS X. One application that will do this is called DVRFlashX I believe. The key is then finding the firmware, which is platform agnostic.
    BTW, removing the drive wouldn’t void the warranty on your Mac but messing with the firmware certainly will void the warranty on the drive.
    Our primary concern remains SuperDrive media disc burn quality .. while you do appear to share the same concern as well as speed performance. Mr Haigh's only concern appears to be speed .. and here we may have missed any opportunity .. since the MATSHITA DVD-R UJ-845C
    SuperDrive is a later designation and the speed performance specifications showing on the apple web-site are likely consistent with current performance capabilities of that SuperDrive and later .. including yours ?
    Mr H may have indeed received marketing materials that promised 8x while actually receiving a 4x SuperDrive .. which only performs at 2x unless exceptional media disc(s) .. so he does have a legitimate claim concerning performance. Do we ?
    What has us fully curious is whether he can burn quality media disc(s) with his new SuperDrive ..
    (Update 24/12/2005 07:10pm (+11 GMT)
    Well, it seems that Apple have decided to replace my hardware. I've started the proceedings yesterday and will hopefully get some news in the new year as to what they are going to replace. At the moment, I'm looking to send in the 12" Powerbook for a replacement, then see what changes in the mac mini side of things. I'm not going to accept the same DVD drive - as we all know the problems with the UJ-835. Stay tuned for more details as they come to hand.) .. http://superdrive.crc.id.au/
    .. which would likely be the same as yours .. now that should prove an interesting outcome .. which he seems likely to voluntarily report and will be the essence of any enquiries from us in the near foreseeable future assuming Mr Haigh is forthcoming in his SuperDrive computing developments.
    Mr Haigh may have begun to scratch the surface (so to speak) .. and find the more serious problem is that no matter how fast or slow the SuperDrive .. reliable media disc burns are a fantasy !
    As yet no update .. almost three months .. could the delay by Apple could have something to do with the model identification of any replacement DVD burner .. if they use an UJ-845 .. then all **** could break loose as Apple users realise (such as we) they do have the same DVD burner and (in a Mac mini) are limited to 4x maximum speed DVD media disc burning performance .. so another designation may be required .. one that already delivers 8x DVD burns .. bit of a mess really .. and the latest Mac mini SuperDrive sports 8x DVD R media burn speed.
    We are curious about you too, dear reader .. are you satisfied with your non Apple disc media burn quality ? We are able to openly admit that we are dissatisfied with our non Apple disc media burn output quality.
    We are currently satisfied with the Apple DV R disc media burn quality. However at a price of premium dollars and an unexplained media burn verification failure message.
    Burn speed, we nonchalantly confess, is not our greatest concern, and, for now, falls to a lower priority of importance with us.
    For now the matter is at rest with us.
    How about you ?
    Yours Sincerely

    PS. .. helping to explain the confusions surrounding the Mac mini SuperDrive is this extracted from ..
    http://en.wikipedia.org/wiki/Mac_mini
    October 2005–February 2006
    Multiple reports exist that the Mac mini was quietly upgraded in October 2005 to 64 MiB VRAM, and either a 1.33 GHz (up from 1.25 GHz) or 1.5 GHz G4 (up from 1.42 GHz) processor, with 512 MiB of PC3200 RAM while underclocking it to PC2700. The 80 GB drive is currently a Seagate Momentus 5400.2 ST9808211A, which runs at 5400 RPM with an 8 MiB cache. The SuperDrive is a MATSHITA DVD-R UJ-845, which supports +R DL burning, and may also have unofficial support for DVD-RAM. Apple did not revise the official specifications on their web site. This may be to avoid issues with discounting or discontinuing of old stock.
    Well .. whatever .. we use a MATSHITA DVD-R UJ-845C SuperDrive .. wouldn't that mean we have +R DL feature too ? .. probably not judging by the following explanations .. sort of .. and yes you could grab the mac_min.pdf service manual and do your own upgrading and overclocking as it pleases you .. try google for more info.

    Mac Mini Part 11

    Stealth Upgrade
    Xxxxxx Xxxxxxxx
    I recently received the SuperDrive Mac Mini that I ordered from Amazon the day after Christmas. To my delight, my Mini contains a 1.5 GHz PPC and 64MB of video RAM.
    The SuperDrive is listed as a Panasonic UJ-845. According to Panasonic's web site this drive is supposed to allow DVD-RAM writing (and I assume reading). Has anyone attempted to use DVD-RAM discs with this drive under 10.4.3?
    Xxxxxx Xxxx
    I also have a new SuperDrive mini with the same specs, and note that the UJ-845 drive doesn't include DVD-RAM capability, though as Gordon notes the OEM Panasonic drive does. However, Panasonic's spec page is for the UJ-845-B drive, and I expect that the one in the mini is instead a special version of the UJ-845 that Panasonic made for Apple with DVD-RAM disabled. For some reason Apple doesn't seem to want to support DVD-RAM, which is a pity. I believe the drive will work with DVD-RAM discs, but treat them like DVD-RW, requiring complete erasure every time they're used, rather than allowing addition and subtraction of individual files, which is what makes DVD-RAM a great backup/exchange medium, especially for travelers.
    My new PowerBook came with an Apple-labeled Panasonic UJ-825-C drive, which System Profiler saw as simply "UJ-825" and which didn't include DVD-RAM although Panasonic's specs showed it; I replaced it with an 825-B I got on eBay, which System Profiler sees as "845-S" and which now does DVD-RAM even without Patchburn. Note that the 825 is two generations earlier than the current 845/846 drive (whose new feature is DL burning); DVD-RAM has been available for a long time, but Apple has been using special versions of the drives without it.
    How to exactly determine the capabilities of your drive: Insert a disc (any type, CD or DVD, but not a blank recordable disc that has to be formatted), open Disk Utility, and on the left side select the drive (not the disc in the drive), then look in the lower right side of the window where it says "Capabilities". You may have to widen the window to see the whole list, as it doesn't wrap for some reason. If it says "DVD-RAM" in the list, the drive should do DVD-RAM discs as they are meant to be used: like a 4GB floppy disk, they must be formatted once, then can be used as "random access media" (RAM). Doesn't matter what kind of disc you put in the drive; any type will make the drive appear in Disk Utility, which will then show its capabilities.
    FOLLOWUP: I opened up the Mac Mini, and found the SuperDrive is an Apple label "UJ-845C", presumably a special version of the 845 with DVD-RAM disabled, unlike the UJ-845-B spec'd at the Panasonic site.
    [MacInTouch]
    We just received a middle-model Mac Mini - 80GB/512MB/AirPort+Bluetooth/Tiger - ordered from Amazon (currently $519.99 after rebate) and were pleased to find that it is one of Apple's "stealth" upgrades, where the label belies the actual specifications. Apple shows it as a 1.42GHz model, but it's actually running at 1.5 GHz, according to System Profiler.
    It has a Seagate ST9808211A hard drive, which is a 5400-RPM model (better than the dog-slow 4200-RPM drives Apple started shipping sometime after the original Mini models debuted).
    The optical drive is a Matsushita CW-8124, a Combo drive with 24X CD writing and reading and the ability to read DVD-R and DVD-RW, as well as DVD-ROM, at 8x.
    System Profiler shows 64 MB of video RAM - double Apple's specified amount - for the "ATY,RV280" graphics card (ATI Radeon 9200) on an AGP bus, supporting display rotation and Quartz Extreme but not Core Image.
    (For what it's worth, we found that we could not connect a Dell 1704FPT to the digital video port while an analog video cable was connected; after removing the analog cable, the Dell works beautifully with the Mini's DVI video. The Dell display also worked fine with analog video via the adapter included with the Mini.)
    We also tried a WiebeTech Maxelerate hard drive enclosure but found it unpleasantly noisy, even in a special reduced-RPM version the company offers customers who raise the issue. By contrast, the miniStack we previously reviewed is virtually silent with the same hard drive inside.
    Xxx Xxxxxxx
    While this isn't the first time I've seen this type of 'error' from Apple, or other firms, this particular incident seems to have gone beyond the typical example, and I'm beginning to wonder if it is more than just an overlap in an otherwise complicated process.
    I've done my share of OEM documentation, including manuals, labels and cartons. I know how hard it is to maintain reality in this regard. But in this case, it seems to me that the mismatch between the inside and the outside of the package has gone beyond the norm, and I'm wondering if someone along the line has simply decided to live with it, rather than deal with it up front. I can see this saving money...changes cost more than just the ink - it takes time and planning to overcome a spec change and cover all the bases.
    I wouldn't be surprised if someone in a position to decide hasn't simply elected to run out the materials without implementing changes. After all, the customer gets more than they expect, which can be favorable publicity, and we all know the saying "any publicity is good, and good publicity is even better".
    On the other hand, it can be a minefield to fess up. Once word gets out, customers start hand-picking the good from the better, taking the higraded units and leaving the rest as floatsom. Or they buy the downgrade for less, then return it shortly thereafter, demanding the up while refusing to pay more.
    Let's just hope the sun keeps shining on this particular parade, and no one decides to claim fraud. All it would take is one competitor with a surplus of over-eager attorneys, and Apple would be forced to apologize for over-stuffing the golden goose.

    We have come to appreciate the SuperDrive is all about the firmware .. but have no new firmware to apply .. in fact .. our research to date shows that we have been unable to find the Matshita SuperDrive at all online and cannot confirm specifications .. neither could we locate the specifications at www.apple.com.au .. which is just plain odd.
    A third look has provided ... from www.apple.com/macmini/specs.html ..
    Storage
    * One of the following optical drives:
    o Slot-loading Combo drive (DVD-ROM/CD-RW): reads DVDs at up to 8x speed, writes CD-R discs at up to 24x speed, writes CD-RW discs at up to 16x speed, reads CDs at up to 24x speed
    o Optional SuperDrive (DVD±RW/CD-RW): writes DVD-R discs at up to 4x speed, writes DVD-RW discs at up to 2x speed, writes DVD+R discs at up to 4x speed, writes DVD+RW discs at up to 2.4x speed, reads DVDs at up to 8x speed, writes CD-R discs at up to 16x speed, writes CD-RW discs at up to 8x speed, reads CDs at up to 24x speed
    Where were you able to establish your SuperDrive (burning) specifications ?
    Writer's note : .. some things change .. and so have the Apple Mac mini SuperDrive burner specs changed .. since recording those detailed above. In fact .. they read like they maybe should have all along .. 8x DVD R media burn speed. DL is a bonus. Can anyone tell us what the drive designation is please ?
    CRC says: ".. This limits burn speed to 4x for Mac Minis and 8x for Powerbooks.".
    While speed matters .. and it does .. you appear to have exactly the same media disc burning problems that we are experiencing .. failed verification(s) .. and for us .. in short .. complete DVD-R media disc burned rejection from the Apple OS X.
    Do we .. in actual fact .. have two separate operating challenges here .. speed of burn and quality of burn .. any burn ? Speed was not our first priority .. quality is .. now we figure that at any speed the burn quality is anywhere from dubious to coaster.
    CRC says: ".. The UJ-835 that Apple use is firmware limited to suit various bits of hardware that they want to put together. The burner in the Mac Mini is the exact same model as the one in the PowerBooks. Apple load a 4x firmware on the Mac Mini, and an 8x firmware on the PowerBook drives.
    My bet is that this is for marketting reasons only. ".

    My parents have a mini and my has one of the PowerBooks. Confirmed the drives are Matsushita UJ-835. They have never had an issue burning DVDs. Confirmed it by burning DVDs last night on the wife’s 12″ PowerBook.
    As far as updating the Firmware in your optical drives, no, you do not have to remove them from the machines to update their firmware. I’ve updated the firmware on my optical drives (for Region Free and/or speed gains) via the GUI in Mac OS X. One application that will do this is called DVRFlashX I believe. The key is then finding the firmware, which is platform agnostic.
    BTW, removing the drive wouldn’t void the warranty on your Mac but messing with the firmware certainly will void the warranty on the drive.
    Our primary concern remains SuperDrive media disc burn quality .. while you do appear to share the same concern as well as speed performance. Mr Haigh's only concern appears to be speed .. and here we may have missed any opportunity .. since the MATSHITA DVD-R UJ-845C
    SuperDrive is a later designation and the speed performance specifications showing on the apple web-site are likely consistent with current performance capabilities of that SuperDrive and later .. including yours ?
    Mr H may have indeed received marketing materials that promised 8x while actually receiving a 4x SuperDrive .. which only performs at 2x unless exceptional media disc(s) .. so he does have a legitimate claim concerning performance. Do we ?
    What has us fully curious is whether he can burn quality media disc(s) with his new SuperDrive ..
    (Update 24/12/2005 07:10pm (+11 GMT)
    Well, it seems that Apple have decided to replace my hardware. I've started the proceedings yesterday and will hopefully get some news in the new year as to what they are going to replace. At the moment, I'm looking to send in the 12" Powerbook for a replacement, then see what changes in the mac mini side of things. I'm not going to accept the same DVD drive - as we all know the problems with the UJ-835. Stay tuned for more details as they come to hand.) .. http://superdrive.crc.id.au/
    .. which would likely be the same as yours .. now that should prove an interesting outcome .. which he seems likely to voluntarily report and will be the essence of any enquiries from us in the near foreseeable future assuming Mr Haigh is forthcoming in his SuperDrive computing developments.
    Mr Haigh may have begun to scratch the surface (so to speak) .. and find the more serious problem is that no matter how fast or slow the SuperDrive .. reliable media disc burns are a fantasy !
    As yet no update .. almost three months .. could the delay by Apple could have something to do with the model identification of any replacement DVD burner .. if they use an UJ-845 .. then all **** could break loose as Apple users realise (such as we) they do have the same DVD burner and (in a Mac mini) are limited to 4x maximum speed DVD media disc burning performance .. so another designation may be required .. one that already delivers 8x DVD burns .. bit of a mess really .. and the latest Mac mini SuperDrive sports 8x DVD R media burn speed.
    We are curious about you too, dear reader .. are you satisfied with your non Apple disc media burn quality ? We are able to openly admit that we are dissatisfied with our non Apple disc media burn output quality.
    We are currently satisfied with the Apple DV R disc media burn quality. However at a price of premium dollars and an unexplained media burn verification failure message.
    Burn speed, we nonchalantly confess, is not our greatest concern, and, for now, falls to a lower priority of importance with us.
    For now the matter is at rest with us.
    How about you ?
    Yours Sincerely

    PS. .. helping to explain the confusions surrounding the Mac mini SuperDrive is this extracted from ..
    http://en.wikipedia.org/wiki/Mac_mini
    October 2005–February 2006
    Multiple reports exist that the Mac mini was quietly upgraded in October 2005 to 64 MiB VRAM, and either a 1.33 GHz (up from 1.25 GHz) or 1.5 GHz G4 (up from 1.42 GHz) processor, with 512 MiB of PC3200 RAM while underclocking it to PC2700. The 80 GB drive is currently a Seagate Momentus 5400.2 ST9808211A, which runs at 5400 RPM with an 8 MiB cache. The SuperDrive is a MATSHITA DVD-R UJ-845, which supports +R DL burning, and may also have unofficial support for DVD-RAM. Apple did not revise the official specifications on their web site. This may be to avoid issues with discounting or discontinuing of old stock.
    Well .. whatever .. we use a MATSHITA DVD-R UJ-845C SuperDrive .. wouldn't that mean we have +R DL feature too ? .. probably not judging by the following explanations .. sort of .. and yes you could grab the mac_min.pdf service manual and do your own upgrading and overclocking as it pleases you .. try google for more info.

    Mac Mini Part 11
    January 9, 2006
    Stealth Upgrade
    Xxxxxx Xxxxxxxx
    I recently received the SuperDrive Mac Mini that I ordered from Amazon the day after Christmas. To my delight, my Mini contains a 1.5 GHz PPC and 64MB of video RAM.
    The SuperDrive is listed as a Panasonic UJ-845. According to Panasonic's web site this drive is supposed to allow DVD-RAM writing (and I assume reading). Has anyone attempted to use DVD-RAM discs with this drive under 10.4.3?
    Xxxxxx Xxxx
    I also have a new SuperDrive mini with the same specs, and note that the UJ-845 drive doesn't include DVD-RAM capability, though as Gordon notes the OEM Panasonic drive does. However, Panasonic's spec page is for the UJ-845-B drive, and I expect that the one in the mini is instead a special version of the UJ-845 that Panasonic made for Apple with DVD-RAM disabled. For some reason Apple doesn't seem to want to support DVD-RAM, which is a pity. I believe the drive will work with DVD-RAM discs, but treat them like DVD-RW, requiring complete erasure every time they're used, rather than allowing addition and subtraction of individual files, which is what makes DVD-RAM a great backup/exchange medium, especially for travelers.
    My new PowerBook came with an Apple-labeled Panasonic UJ-825-C drive, which System Profiler saw as simply "UJ-825" and which didn't include DVD-RAM although Panasonic's specs showed it; I replaced it with an 825-B I got on eBay, which System Profiler sees as "845-S" and which now does DVD-RAM even without Patchburn. Note that the 825 is two generations earlier than the current 845/846 drive (whose new feature is DL burning); DVD-RAM has been available for a long time, but Apple has been using special versions of the drives without it.
    How to exactly determine the capabilities of your drive: Insert a disc (any type, CD or DVD, but not a blank recordable disc that has to be formatted), open Disk Utility, and on the left side select the drive (not the disc in the drive), then look in the lower right side of the window where it says "Capabilities". You may have to widen the window to see the whole list, as it doesn't wrap for some reason. If it says "DVD-RAM" in the list, the drive should do DVD-RAM discs as they are meant to be used: like a 4GB floppy disk, they must be formatted once, then can be used as "random access media" (RAM). Doesn't matter what kind of disc you put in the drive; any type will make the drive appear in Disk Utility, which will then show its capabilities.
    FOLLOWUP: I opened up the Mac Mini, and found the SuperDrive is an Apple label "UJ-845C", presumably a special version of the 845 with DVD-RAM disabled, unlike the UJ-845-B spec'd at the Panasonic site.
    [MacInTouch]
    We just received a middle-model Mac Mini - 80GB/512MB/AirPort+Bluetooth/Tiger - ordered from Amazon (currently $519.99 after rebate) and were pleased to find that it is one of Apple's "stealth" upgrades, where the label belies the actual specifications. Apple shows it as a 1.42GHz model, but it's actually running at 1.5 GHz, according to System Profiler.
    It has a Seagate ST9808211A hard drive, which is a 5400-RPM model (better than the dog-slow 4200-RPM drives Apple started shipping sometime after the original Mini models debuted).
    The optical drive is a Matsushita CW-8124, a Combo drive with 24X CD writing and reading and the ability to read DVD-R and DVD-RW, as well as DVD-ROM, at 8x.
    System Profiler shows 64 MB of video RAM - double Apple's specified amount - for the "ATY,RV280" graphics card (ATI Radeon 9200) on an AGP bus, supporting display rotation and Quartz Extreme but not Core Image.
    (For what it's worth, we found that we could not connect a Dell 1704FPT to the digital video port while an analog video cable was connected; after removing the analog cable, the Dell works beautifully with the Mini's DVI video. The Dell display also worked fine with analog video via the adapter included with the Mini.)
    We also tried a WiebeTech Maxelerate hard drive enclosure but found it unpleasantly noisy, even in a special reduced-RPM version the company offers customers who raise the issue. By contrast, the miniStack we previously reviewed is virtually silent with the same hard drive inside.
    Xxx Xxxxxxx
    While this isn't the first time I've seen this type of 'error' from Apple, or other firms, this particular incident seems to have gone beyond the typical example, and I'm beginning to wonder if it is more than just an overlap in an otherwise complicated process.
    I've done my share of OEM documentation, including manuals, labels and cartons. I know how hard it is to maintain reality in this regard. But in this case, it seems to me that the mismatch between the inside and the outside of the package has gone beyond the norm, and I'm wondering if someone along the line has simply decided to live with it, rather than deal with it up front. I can see this saving money...changes cost more than just the ink - it takes time and planning to overcome a spec change and cover all the bases.
    I wouldn't be surprised if someone in a position to decide hasn't simply elected to run out the materials without implementing changes. After all, the customer gets more than they expect, which can be favorable publicity, and we all know the saying "any publicity is good, and good publicity is even better".
    On the other hand, it can be a minefield to fess up. Once word gets out, customers start hand-picking the good from the better, taking the higraded units and leaving the rest as floatsom. Or they buy the downgrade for less, then return it shortly thereafter, demanding the up while refusing to pay more.
    Let's just hope the sun keeps shining on this particular parade, and no one decides to claim fraud. All it would take is one competitor with a surplus of over-eager attorneys, and Apple would be forced to apologize for over-stuffing the golden goose.

  • SuperDrive Media Disc(s) .. Assist ...

    Dear Apple Mac Mini User forum participants
    b Macmini SuperDrive : Matsushita DVD-R UJ-845C
    How do we confirm the correct read/writable disc(s) media for our Mac mini ?
    We have searched widely .. specifically .. and generally .. online.
    And we come away with no new definitive knowledge. Others
    have trialled and erred .. and learned .. and reported. But still
    we are ill-informed about which particular media we should
    be restricting ourselves to use in our Mac mini.
    Are you able to assist by sharing your garnered information(s)
    about the correct media(s) for the Mac Mini Superdrive.
    We seek your illumination by kind response, if you will.
    Point us to the worthy online repositories or share your personally
    accrued gems of optical SuperDrive media disc management.
    And finally, for now, we would like to hear your formula for establishing
    the minimum specification to share your media disc(s) among your Mac
    computers in use and even with an XP machine, from time to time.
    Establishing the upper performances and the lower compatibilities would
    provide a practicable strategy to managing machine restricted and machine
    to machine informations sharing by optical drive media disc(s).
    Positively thanked will you be.
    very much obliged,
    Stuart .

    Dear Apple Mac mini user discussions participants
    Thank you to everyone who has constructively added to
    the body of useful knowledge now available in this
    humble thread. Your contributions are genuinely prized.
    Gems.
    We have read and re-read your entries, acting where
    able, to discover more about the true capabilities of
    the Mac mini SuperDrive mentioned. Along the way, we
    have discovered a few many other related and relevant
    aspects to the personal industry of media disc burning.
    Here is the Apple Mac mini ..
    About This Mac ..
    More Info ..
    Disc Burning ..
    MATSHITA DVD-R UJ-845C:
    Firmware Revision: DPP9
    Interconnect: ATAPI

    Media: No
    One of the informations we seek is the speeds capacities
    of the SuperDrive mentioned. More frequently now .. in
    the stores .. you find speed rated disc media for
    burning. What are the rated speeds of the Mac mini
    SuperDrive and media ?
    What does CD-TAO mean ? TAO : TrackAtOnce
    What does CD-SAO mean ? SAO : SessionAtOnce
    What does DVD-DAO mean ? DAO : DiscAtOnce
    What does .. Media: No .. mean ?
    From here we begin to discover compatible media ..
    the original mission.
    Online .. here and elsewhere .. we are educated by the
    many who have trialed and erred before us. Most demanded
    manufacturer of disc burning media is 'Taiyo Yuden(s)'.
    Made in Japan. Taiyo Yuden Company Limited is mentioned
    by www.cdfeaks.com WIKI as the most preferred media too.
    Most recommended brand name of disc burning media is
    Verbatim.
    We searched for Taiyo Yuden(s) media in our geographical
    locale. Rare as hens teeth. Sold out before arrival.
    Premium price no deterrent to those in the business of
    quality disc burning. We settled for a couple of
    Verbatim DVD+RW media discs. Made in Taiwan. Every disc
    we could locate in retail was either made in Taiwan or
    made in Singapore.
    We began our media disc burning adventure by applying
    the native OS X Tiger 10.4.2 disc burning applications.
    Finder and Disk Utility. We bothered not with itunes,
    iphoto, since our mission is data. Problems emerged
    early. From the log file automatically kept by Disk
    Utility (top right hand corner of the DU window) you are
    able to read for yourselves the two error messages
    reported as operations failed. Error messages ...
    Finishing burn
    Verifying burn...
    Verifying
    Burn failed
    Verification of the burn failed.

    Verification of the burn failed..

    Preparing data for burn
    Opening session
    Finishing burn
    Burn failed
    The device failed to calibrate the laser power level
    for this media. Unable to burn “backup xxxxxxxxxxxxxx

    laser power level for this media..
    Finder media disc burn error message ...
    This disc did not verify correctly and is unreliable.
    Because the disc is unreliable, discard it and try again
    using a new, blank disc. (Error code: 0x80020063)
    Success message - without verification ...
    Burn completed successfully
    Image “backup xxxxxxxxxxxxxx xx.xx.xxx.dmg” burned
    successfully.
    Operations failure .. we quickly discovered .. does not
    mean media disc burn total failure.
    All media disc burn operations were 'successful'. And,
    as soon as we unticked Verify data at end of disc burn
    (DU), we were regularly greeted with successful media
    disc burn dialogue affirmation. Encouraging .. and
    further confirmed as we examined the data burned and
    satisfied ourselves of the totality of the writing
    event. Otherwise .. DU had zero challenges media disc
    burning and reading burned media and copying data files
    back onto the originating apple mac mini hard disk
    drive. Remember that DU is limited to media disc burning
    in apple format only and multi-sessioning where on
    screen you will be greeted with individual icons
    representing each session burned on the same media disc
    burned.
    However, things went south far to soon and without very
    apparent reason. The DVD+RW was suddenly and perpetually
    rejected by the SuperDrive. No doubt .. the more
    informed among you are smiling and nodding knowingly ..
    at our novice and amateur opening efforts. Useless disc.
    You may be able to pinpoint the moment of coaster
    creation from the supplied error messages logged.
    We imagine that the lack of verification availability ..
    always displayed with an unsuccessful burn message,
    every time .. points directly to media disc quality.
    Unusable disc an eventual certainty. Perhaps.
    Every disc burned delivered an unsuccessful burn message
    whenever Verify data burned was ticked. Finder media
    disc burning does not provide apparent opportunity to
    switch off verification. Read-on .. if you are
    interested to discover our further media disc burning
    experiences and experimentations.
    We re-examined the apple computer help system from DU
    and learned that DVD+RW is the favoured alternate re-
    writeable format disc for DVD re-writing intended to
    replace the capabilities of DVD-RW and DVD-RAM and
    provide higher compatibility with set-top players ..
    though some DVD drives or applications may not support
    recording to this disc format. At the store .. we re-
    read the retail store chart by Verbatim on DVD options
    and learned of media designation purpose distinctions.
    Still .. we appear to have chosen within the SuperDrive
    capabilities. Another disc we should like to sample is
    the DVD-RAM disc .. which is not specifically mentioned
    as compatible media .. are you able to clarify whether
    Mac mini users with the mentioned SuperDrive
    MATSHITA DVD-R UJ-845C are able to use this designation
    ? And the reason for the question is that we have
    discovered a DVD-RAM disc available from a Japanese
    manufacturer. Premium price at the retailer .. assuming
    premium quality too. Appears, however that we are unable
    to use DVD-RAM media burn disc(s).
    After media disc burning the DVD+RW disc we then fed the
    written disc (and at that time, readable - by the
    originating Mac mini machine) to the iMac DV SE
    (graphite) running OS X 10.4.3 Tiger to confirm
    compatibility. Nightmare on Apple street. Barely able to
    read the media disc burned .. we eventually had to force
    the iMac cough the DVD+RW disc back out by manually
    restarting the iMac machine (side button) and holding
    the mouse button down on start-up. Disc retrieved ..
    safely. First time ever in five years of ownership ..
    since new. Bummer. To eliminate speculation of poor iMac
    DV SE drive performance we set about throwing other CD
    and DVD discs at the machine. Perfect. From the iMac ATA
    Device Tree - ATA Bus ... (no media disc burning capability)
    MATSHITADVD-ROM SR-8184:
    Model: MATSHITADVD-ROM SR-8184
    Revision: AA32
    Serial Number:
    Detachable Drive: No
    Protocol: ATAPI
    Unit Number: 1
    Socket Type: Internal
    Disk Utility and Finder are limited media disc burning
    applications. DU creates multi-session disc by burning
    separate instances that manifest as separate disc icons
    on the desktop. Operationally limiting and eventually
    problematical. iMac DV SE showed only the first media
    disc burn of a multi-session disc burned. DU is limited
    to media disc burning in Mac OS format only too.
    We returned the DVD+RW discs to the retailer .. one
    opened and used and fully rejected and the other
    unopened. Instead we chose to step down to Verbatim
    CD-RW discs .. made in Taiwan. We continue with our
    experimentations. Finder help reveals more about disc
    burning and under; "I got an 'unknown error' message
    while burning a CD or DVD disc" we find two links ..
    Apple Service & Support article: Problems burning discs

    Mac OS X: "Unknown Error -2147352480" when burning CD-R,
    CD-RW, or DVD-R media Learn how to troubleshoot burn
    underrun protection issues ("Unknown Error -2147352480"
    alert) when burning a disc. This document applies to Mac
    OS X 10.2 or later.
    Try these tips:
    * Specify a burn speed that is less than the maximum
    speed rating for the optical drive.
    * Quit open applications you are not using. Open
    applications are marked with a triangle in the Dock.
    * Once a burn session has started, do not move, bump,
    or vibrate the computer.
    * Do not put labels on blank discs before burning them.
    * Use blank discs that are rated for the burn speeds of
    your drive, or consider using a different brand of media.
    * See "Macintosh: Factors That Affect Writing to or
    Reading From Optical Media".
    Your computer may also benefit from installing additional
    memory (RAM) or a higher-bandwidth system interface for a
    burning device (such as SCSI).
    You might also consider having the optical media device
    tested by an Apple Authorized Service Provider.
    Additional information
    The Console utility or log may report:
    "-2147352480 = 0x80020060 = kDRBurnUnderrunErr = Device
    drained buffer without burn underrun protection"
    Low disk space or RAM availability issues can lead to this.
    These are some clues that this might be the case:<
    * The issue more often occurs during the burn process.
    * The failed burn more often leaves data partially
    written to the disc, and he disc can't be reused.
    Physical source of these issues can lead to burn failures
    and can sometimes be identified when:
    * The issue more often occurs at the start of the burn
    process.
    * The failed burn session more often leaves the media
    untouched and ready to be burned. (It is still blank.)
    * The burn starts, but an external incident interrupts
    the session.

    "Macintosh: Factors That Affect Writing to or Reading From Optical Media" ...
    Factors that affect writing to or reading from optical media
    This document discusses things can affect your computer's
    ability to write CD and DVD discs, and what can potentially
    affect their being read by other computers and consumer
    electronics equipment.
    Several things can affect the mastering of recordable media
    and the ability to read them by other devices. These factors
    equally apply to CD-R, CD-RW, DVD-R, and DVD-RW media.
    To consistently achieve successful burns, be aware of these
    factors
    The source for the media
    Third-party discs that conform to the specifications of the
    drive should operate as expected. However, since Apple has
    not physically tested these discs, you should contact the
    manufacturer if full compatibility cannot be achieved.
    Apple-brand discs are tested and qualified for use with
    Apple-installed optical drives and are fully compatible.
    The optical drive used to master the media
    Earlier drives may not work with some later, high speed
    media. Use discs recommended by your drive's manufacturer.
    Make sure you have installed any firmware updates available
    for the drive. Some updates may address media compatibility
    issues, or update the function of the drive in other ways.
    The software used to master the media
    Make sure the application software you use to master the
    discs is up to date. Make sure the options you choose in
    the application, such as the burn speed, work with the
    drive and the media you are using. Varying the burn speed
    may affect the compatibility of the media in the playback
    device. This may make a difference in the accuracy of the
    mastering of an audio CD or DVD. Burning applications often
    perform a verification after the burning process is complete.
    This ensures that the final disc is ready for playback.
    If the verification fails, try choosing a slower burn speed.
    The connection method for your optical drive
    If your burner is connected via USB, you may not be able to
    burn at the highest speed the drive is capable of using.
    Trying to burn at too high of a speed may lead to a failed
    burn because there is not enough bandwidth on the bus.
    If you have a SCSI burner, make sure the SCSI cabling is
    configured correctly, and that the SCSI chain is properly
    terminated. Issues may result from improper termination.
    Also, make sure you use properly-shielded cables to connect
    the burner to the computer.
    To successfully use your burned media, be aware of these factors
    The source of the media
    In general, if you are able to successfully burn discs in a
    drive, that drive should be able to read the same discs without
    an issue.
    Note: Apple optical drives work with standard 650 MB-capacity
    discs, but not all drives work with 700 MB-capacity (80 or 90
    minute) discs.
    The optical drive used to read the media
    Earlier optical drives may have issues reading modern media.
    Early DVD-ROM drives, for example, may not read burned DVD-R
    or DVD-RW discs. Some may read DVD-R, but not DVD-RW. This is
    true for consumer audio CD players, car audio players, and
    DVD-Video players, too. Depending on when the drive was
    manufactured, it may or may not be compatible with certain
    burned media. Check the documentation that came with the player,
    or check with the manufacturer for more information. A firmware
    update may be available that improves compatibility. Even if it
    is considered "compatible" with certain media, you may encounter
    issues with some brands of media, or issues with media burned at
    certain speeds.
    The software used to read the media
    You may find that software designed to copy data to discs cannot
    successfully copy video or audio to discs. Make sure you are
    using a current version of the application, and that the software
    can copy the kind of data you are working with.
    For best success in reading media, use the latest version of
    the Mac OS. Also, make sure that you burn the disc in a format
    that can be used by the operating system that will read the disc.
    For example, a CD burned in Mac OS Extended (HFS Plus) format
    may not work with a Microsoft Windows-based computer.
    If a disc's format is not normally recognized by the computer's
    operating system, you may need to install software that allows
    the computer to recognize it.

    Finder help also explains about burning blank CD or DVD
    disc(s) and states that it will create burned disc(s)in
    'hybrid' format that can be read by most computers,
    including Windows computers. The (burned) disc contains
    these filesystem: HFS+, ISO-9660 with Rock Ridge, and
    Joliet with Rock Ridge. However .. "The names of files,
    folders, and the disc can't be changed after the CD is
    burned." So, a CD-R or DVD-R would seem the appropriate
    media disc(s) to use as they cannot be (erased and) re-
    written .. on any machine. [ but they can be written
    until full with other softwares and on other operating
    systems .. e.g. XP ]
    We used CD-RW to experiment with this capability .. by
    media disc burning data files to find out what we could
    do after the first Finder burn. Initially recognized as
    a CDR media disc. As you, dear reader, are by now, well
    aware, media burn automatic verification failed.
    Automatic ejection occurred after the burn and at the
    (usual) verification failure message from Finder.
    Re-insertion (after a delayed period) showed the CD-RW
    disc to be CD-RW Untitled CD .. even though we had
    titled the disc at dialogue box burn time. One folder
    and zero nested folder or data files content were shown
    as recorded in the Finder window. We know something is
    on the disc because the usage amount is shown as 353.6MB
    on the desktop icon. Second attempt to burn gave
    message: Insert a blank disc to begin. So CD-R is better
    value (read: cheaper) media than CD-RW for Finder burns.
    You can use use DU to erase the CD-RW. DU agrees with
    the media burned disc volume usage.
    Finder is doubly confusing because of two apparently
    colliding help entry explanations.
    Under: Disc burning options are dimmed or unavailable ..
    is the explanation: If the entry contains "-R", your
    computer can write to a CD-R or DVD-R disc only once. If
    the entry contains "-RW", your computer can erase a CD-R
    or DV-R disc and write to it again.
    However ..
    Under : I can't burn files on my recordable CD or DVD
    disc .. is the explanation: If the entry contains "-R",
    your computer can write to a CD-R or DVD-R disc only
    once. If the entry contains "-RW", your computer can
    erase a CD-RW or DVD-RW disc and write to it again.
    Personal experience proves the latter explanation to be
    the more correct one. We are unable to erase a CD-R or
    DVD-R disc on either Mac or XP machines. Whew.
    Are we missing something here ?
    Or is that the correct facts of the designations ?
    Finder also provides a run-down of Types of recordable
    CD and DVD media.
    Types of recordable CD and DVD media
    If your computer has an internal or external recordable
    optical drive supported by Apple, you can "burn" or
    record your favorite music, applications, documents,
    digital photos and video, and other digital files to
    recordable CD and DVD discs. You can create your own
    music CDs and play them on a standard audio player, or
    create DVDs with movies and slideshows and play them on
    a DVD player.
    There are several types of recordable CD and DVD media:
    • DVD-R discs hold about 4.7 GB of information.
    You can burn files on a DVD-R disc using the Apple
    SuperDrive. DVD-R discs are not reusable; you can burn
    files on them only once.
    • DVD+R is an alternate DVD Recordable write-once
    format. Some DVD drives or applications may not support
    recording to this disc format.
    • DVD-RW discs hold about 4.7 GB of information on
    each side. If you have an Apple SuperDrive, you can read
    information on these discs, but you can't burn files on
    them using Mac OS X. DVD-RW discs are reusable: you can
    burn files on them, erase them, and then burn again (if
    you have an application that is compatible).
    • DVD+RW is an alternate DVD ReWritable format
    intended to replace the capabilities of DVD-RW and DVD-
    RAM and provide higher compatibility with set-top
    players. Some DVD drives or applications may not support
    recording to this disc format.
    • CD-RW discs come in normal and high-speed
    formats. You can burn files on CD-RW discs using the
    Combo drive (or another supported CD burner). CD-RW
    discs are reusable: you can burn files on them, erase
    them, and then burn again.
    • CD-R discs come in two types. One holds 74
    minutes of audio, or about 650 MB of information. The
    other holds 80 minutes of audio, or about 700 MB of
    information. You can burn CD-R discs using the Combo
    drive (or another supported CD burner).
    For recording audio CDs, it is best to use CD-R discs
    because most standard audio CD players cannot read CD-RW
    discs. For longer-term storage and reliability, use CD-R
    discs.
    You can't burn anything on a CD-ROM or DVD-ROM disc.
    Enter Microsoft Windows XP Professional
    We are .. for once .. fortunate enough to have Microsoft
    Windows XP machine available to us with media disc
    burning hardware installed. Just like the Mac mini .. we
    do not have any other software installed for media disc
    operations, only from the native XP OS supplied tools.
    However .. we quickly discover that the XP machine has
    an edge .. licensed Roxio software integrated into the
    XP OS. And it works well. We discover that the Apple OS
    X media disc burning software Disk Utility .. chooses
    only to format in Apple OS. Meaning .. DU media disc
    burned with Mac mini are only able to be read by Apple
    OS machines. Confirmed by attempting to have the XP
    machine(s) read the disc burned. Unable. But .. media
    discs burned by XP machines are able to be read by the
    Apple machines. Because XP machines native OS media
    disc burning format appears to be an industry standard
    OS independent. Couldn't tell from the available
    information from the XP OS but suspect it is an ISO 9660
    format variation. To be exactly confirmed .. and it will
    be .. because the entire outcome of this mission is to
    arrive at a total media disc burning and sharing
    strategy among Apple and as a matter of operating
    contingency .. XP machines too. Open source
    applications in use by us are deliberately cross
    platform between XP and Apple machines. Data generated
    is able to be swapped or even shared among the machines
    with little or mostly no user operating challenges.
    Focus on productivity. The media disc(s) burned in the
    XP machine reads well in the Apple machines.
    The Finder media burned disc .. mentioned above earlier
    .. CD-RW .. read immediately on the XP machine .. folder
    and data files burned .. all there .. all on display.
    99% able to be copied to the XP machine hard disk .. and
    confirmed as a CD-R formatted disc since only option is
    to erase the disc and not add to the existing content ..
    thanks to the Apple Finder format for the re-use sharing
    limitations. So Apple SuperDrive cannot read it's own
    disc but XP machine can and is able to verify burn by
    way of 99% trouble free copy to XP machine hard disk.
    Here .. we begin to struggle with what is happening in
    our limited media disc burning experience(s).
    Enter Media Disc Burning Software
    Additional software has become necessary to accomplish
    our media compatibility and resource management
    requirement(s) .. and we are surely open to your welcome
    suggestions for software applications that enhance the
    available Tiger OS X applications for dependable
    outcomes.
    Remembering for a moment that we have arrived at almost
    total incompatibility between the two Apple disc media
    drives mentioned after burning disc(s) in the Mac mini
    using DU and Finder and attempting reading in the iMac
    DV SE. We are searching for ways to achieve worthwhile
    compatibility.
    And one way is to use the XP machine to create data
    burned media disc(s) that are instantly able to be
    easily read by both Apples in our humble possession.
    This fact is an earlier discovery .. when migrating
    (again) from the XP realm to Apple heaven. Moving open
    source application data files form the XP realm to
    the Apple iMac DV SE machine was unencumbered. Easy.
    How unprepared we are for the encounter with OS X media
    disc burning tools limitations.
    We go on-line to seek any worthwhile open source media
    burning software for OS X. www.pure-mac.com lists
    several possibilities. We need to burn media disc(s)
    that are able to be read by a wider population of
    computer systems including Apple (OS X) and PC (XP) and
    be fully (re-)used to their manufactured storage
    capacities. A combination of Finder and Disk Utility,
    if you will.
    We quickly learn that Roxio is evidently the developer
    of the supreme media burning software available to Apple
    users. And garner from on-line sources that Roxio is
    favoured by the serious and casual user who demands
    quality.
    For the moment we choose to learn more by trialing less
    expensive media disc burning software(s) to find out
    whether our simple needs (and open source patronages)
    can be met by available applications without unnecessary
    bells and whistles. We may be wasting our time here ..
    if Roxio or similar is favoured by so many and not
    because of the bells and whistles but rather
    because of media disc burning performance quality and
    standards then we are likely to arrive at that same
    destination too. As satisfied Roxio user.

    BurnAgain is one of the programs we chose to experiment
    with to create more standards compatible media disc(s)
    burned. BurnAgain is developed only for the OS X.
    BurnAgain automatically and only formats in ISO 9660
    (Rock Ridge) .. guaranteeing Windows machine
    compatibility. And it does .. so far .. we have used up
    about 5 of the available 10 burns before registration
    should be made with the author. We learn from the
    BurnAgain help system that iTunes burns the same as
    Finder.
    However, BurnAgain focuses only on CD-R and CD-RW media
    .. SuperDrive is capable of more. And you are
    discouraged from mixing media disc burning applications
    to burn the same media disc. BurnAgain prefers you to
    stay the course. DU is the OS X solution to alternate
    media burning (DVD) .. but apple OS format only.
    However, still our iMac is troubled and challenged to
    fully and properly read the BurnAgain media disc(s)
    burned (CD-RW) by the Mac mini .. it couldn't .. but
    eject was a formality and not a crises recovery
    management procedure as before with the DVD+RW disc
    burned by DU on the Mac mini.
    XP machine could read the BurnAgain CD-RW Verbatim
    disc(s) easily and fully .. but copying was about 99%
    accurate (same as Finder). We are writing about 350
    Mbytes of data files recorded on the CD-RW media disc
    with nested folders up to several deep. However,
    subsequent burns to disc(s) wouldn't repeat the same
    data file errors .. meaning if you noted the delinquent
    files then you could just BurnAgain those files and
    expect eventual full disc to hard drive copy success on
    the target machine (XP in our situation) of those
    deliquent datafiles.
    Originating Apple Mac mini machine could read the
    BurnAgain CD-RW verbatim disc(s) easily and fully .. and
    copying was 100% accurate back onto the originating
    Apple Mac mini machine hard disk .. all 350 Mbytes of
    data files .. no error messages reported. Meaning the
    originating machine is performing as expected .. with
    BurnAgain .. but sharing remains a challenge with other
    machines. Particularly iMac DV SE. Remember that Finder
    media disk burned couldn't read again on the Mac mini.
    BurnAgain is clearly an improvement of standards based
    media disc burning .. since originating Mac mini could
    read it's own burn and XP machine 99% accurate too. DU
    is OK if you are confining yourself to Apple machines
    and they can actually read the media disk burned .. only
    originating Mac Mini was able to read it's own burn 100%
    MATSHITA DVD-R UJ-845C is the most modern and capable
    (Super)drive among the five disc media equipped machines
    available here. For now we are confused whether that is
    any advantage or disadvantage.
    We are going to run through the remaining media disc
    burning softwares available from the www.pure-mac.com
    website to determine if our simple needs can be met
    or whether we are required to plumb for the creme deluxe
    (Roxio) and have greatest confidence that our media disc
    burning needs are fully met. We may report back our
    findings to anyone so interested at this forum. Are you?
    We also chose to sample a Verbatim CD-R media disc for
    burning and copying of data files among machines.
    However .. the BurnAgain burn went well .. but the
    copying was problematical to the XP machine hard disk ..
    file copy errors .. and back on to the originating Apple
    Mac mini machine hard disk too .. Error code - 36 (same
    file errors as XP machine). We tried again and met error
    messages from the BurnAgain application .. to the effect
    that BurnAgain would not permit a further media disc
    burn .. even though few hundred megabytes available on
    target media CD-R disc. This outcome .. according to
    Disk Utility help is because: "Mac OS Extended allows
    burning the disc more than once. Formats such as ISO
    allow burning the disc only once." Off to the XP machine
    and burn an additional small file to the disc. Perfect.
    Back to the Apple originating machine .. copy file to
    the Mac mini HD. Perfect. Kept the disc for any future
    file transfers between the XP to the Mac(s) until fully
    used. How confusing .. and .. yes .. frustrating too.
    Burnz is the only other program we choose to sample
    after studying the homepages and value propositions
    and our needs assessment. Thank you to www.pure-mac.com
    for the compilation(s) and accessibilities. Appreciated.
    Burnz developer www.thinkertons.com have other software
    available too. While downloading Burnz media disc burn-
    ing software for trial evaluation .. we browsed Burnerz
    .. another application from thinkertons that is 100%
    free. Burnerz is an informational tool .. and retrieves
    whatever informations available on your system about

    Back to BURNZ
    Burnz has a particular feature that meets our
    requirements and added weight to the application's value
    proposition. You are able to choose the specific optical
    media disc burn format. Five graduations exist.
    Each graduation includes (all) of the lower ranked media
    burn format qualities. Top to bottom sliding scale.
    HFS+
    ISO 9660 Joliet extensions
    ISO 9660 RockRidge extensions
    ISO 9660 level 2
    ISO 9660 level 1
    Visually affirmative .. this feature gives user
    confidence about media disc burned format
    compatibilities. And the website and written materials
    from thinkertons make clear that compatibility is well
    covered for all optical media drives. Exactly what we
    seek. Default is HFS+ which thinkertons encourages you
    to maintain unless you do reason to otherwise change.
    Finally, for now, Burnz writes DVD media disc(s) too.
    Wethinks .. could we go wrong now .. as we progressed to
    practical evaluation. 10 free burns before registration
    is required by thinkertons. Here we go ..
    We chose 407.29mb data files .. application downloads
    and Tiger updates (.dmg, .zip, .bin) .. in one folder
    to brand new Verbatim CD-R (702.82mb available according
    to Burnz) .. and settings to maximum possible speed
    (automatically selected at 16x) .. other selectable
    speed setting is 8x .. and leave disc appendable ..
    verify burned data ON ...
    Burn failed...
    StatusError: -2147352477
    ErrorString: Verification of the burn failed
    RE-inserting the media burned disc gave desktop CDR
    icon with the burn folder named and 406.9 MB usage ..
    Finder (double click on the desktop disc icon) shows
    all 18 items burned .. copy from CDR back to new desktop
    folder showed the appropriate copy dialogue box and
    progress bar without color .. left awhile to see what
    happens ...
    The Finder cannot complete the operation because some
    data in "Gimp-2.2.8.dmg" could not be read or written.
    (Error code -36).
    Error code -36 is becoming an old friend ..
    Repeating the operation minus "Gimp-2.2.8.dmg" ..
    same drill .. offending file "MacOSXUpdate10.4.3.dmg" ..
    repeating minus "MacOSXUpdate10.4.3.dmg" .. same
    drill .. repeating minus "PDFLab.dmg" .. that's three
    out of total 18 so far .. and not one copied from disc
    to desktop .. last chance before coaster designation
    is applied as we get the pattern and the picture ..
    down to 245.9 MB to copy and still no satisfaction ..
    and now number 4 "Firefox 1.0.7.dmg" ..
    Houston .. we have a coaster .. trajectory .. garbage.
    Won't bother trying this disc insert into the iMac.
    However, we troubled ourselves to find out what would
    happen in the XP machine .. same outcome .. yes,
    readable by XP but copy failure to hard disk on the
    larger .dmg files. Not unexpected. Media format
    compatibility confirmed .. just as Burnz promised.
    Repeating the entire exercise with brand new Verbatim
    CD-RW (just to reduce CDR coaster count) .. this time
    at 4x write (automatically determined with no other
    speeds selectable - maximum possible) .. all other
    settings unchanged ... samo .. samo ..
    Burn failed...
    StatusError: -2147352477
    ErrorString: Verification of the burn failed
    RE-inserting the media burned disc gave desktop CDRW
    icon with the burn folder named and 406.9 MB usage ..
    Finder (double click on the desktop disc icon) shows
    all 18 items burned .. copy from CDRW back to a new
    desktop folder showed the appropriate copy dialogue box
    and progress bar color .. copy began immediately and
    reached the end .. Bingo .. we have a winner ! .. or
    do we ? .. Opening 50% of the now copied to desktop .dmg
    files produced an error message: The following disk
    images failed to mount. And for each delinquent .dmg ..
    the same Reason: codec overrun .. quite whatever that is
    meaning .. we appreciate the .dmg is damaged and now
    useless. Always the larger .dmg files .. up to 125 MB.
    On the Apple .. we are down two for two .. let's go
    again with burn verification off .. but first erase the
    disk with DU quick erase .. done .. now regarded again
    as an empty CDR by Finder .. (note that 'Erase disc
    before burning' is an available option in Burnz and on
    the Burn Disc dialogue box .. but it wasn't available
    as soon as the previously burned media disc was
    re-inserted for deleting and re-burning) ..
    No burn failure message .. as expected .. 406.9 MB
    usage on CDRW .. as expected .. Finder shows all
    18 items burned .. copy to desktop .. seemingly
    good .. as before and usual .. opening .. again
    a 50% failure rate .. same message .. same result.
    And in the XP machine .. same for read and copy to HD.
    OK .. let's give it one last go with the .dmg's, .bin's,
    and the .zip files .. by erasing again (with DU again)
    and media disc burning the CD-RW with just one file at
    a time and then copying back to confirm burned file
    integrity .. that's totally 18 burns .. but we shall
    only go as far as 9 file burns and copy back to the
    desktop from the burned media disc .. if all 9 are
    good then we shall assume it would all be good. We
    trial the big .dmg's to begin .. interestingly, erase
    disk before burning is available now and so we use
    that feature rather then DU (perhaps because the
    burn is less than the remaining disc storage available)
    .. is that a bug ? we wonder .. we turn Verify burned
    data ON .. just curious .. we are asked about our erase
    certainty before proceeding .. we click yes ..
    burning .. 97 MB .dmg .. burned (no negative
    verification error message) .. now copying back to
    desktop .. opening .. and .. codec overrun message.
    Finally, for now, we return to our original evaluation
    folders and files trialled with BurnAgain .. and perform
    the same media disc burn and onto the same (new) media
    disc (i.e. CD-RW) from the same batch too .. using Burnz
    .. Verify ON ...
    Burn Failed ... blah
    Copying back to desktop .. copy back is good .. just
    like BurnAgain .. encouraging.
    What that says about the larger .dmg files or perhaps
    any larger (50mb+) files to burn is unclear .. do you
    need even better hardware (media and burner) and
    software ? .. or are you out there in expert land able
    to advise readers how you do exact maximum confidence
    on the larger files media disc burn(s)?
    No DVD media burn disc(s) lying around here, for now,
    so we shall reserve any outcomes for another day of
    evaluations and experimentations.
    BurnAgain and Burnz go head to head .. From the tests
    performed to date we are able to comment from personal
    experimentation and practical experience .. they are
    very much similar quality .. Burnz does DVD's too.
    However, neither managed to accomplish entirely reliable
    media disc burn(s), of use, beyond the originating Mac
    mini SuperDrive .. nor accomplish verification .. is
    that normal ? Or do we have a particular problem ?
    We are back to square one for verifiable media disc
    burning.
    Interestingly .. those 10 free media disc burns
    available .. have only reduced by the number of burns
    without verification .. since negative verification
    appears to not count .. 8 free burns still available ..

    (applied to Os X Finder, BurnAgain and Burnz
    applications)
    We are safely at the point where we can assert that we
    have a potential operating solution for the Mac mini
    media disc burning. However, we remain reliant on our
    XP machine to create media disc burned that can be read
    fully by the iMac DV SE. And we have no confidence to
    date in the ability to share information burned by the
    Mac mini with any other party .. except where we can
    repeat ourselves over several iterations to accomplish
    100% data transfer .. and that means we are confined to
    our home operating computer systems. For now, XP machine
    is required to write a media disc that can then be read
    by the iMac DV SE. (Yes, we do have a Mac to Mac network
    .. but if data is unavailable on either of the Mac
    machine drives then we are required to resort to hard
    media backup) Media disc(s) sampled to date .. Verbatim
    CD-R, CD-RW, DVD+RW .
    Apple quality media pack (8x DVD-R only)*• is available
    at www.apple.com and in our locale. We shall sample the,
    not inexpensive, apple media disc(s) in the near future
    .. and report back. Still the DVD-R is write once. And
    no mention of any CD-RW apple quality media
    availability. Remember ...
    *• DVD-R discs hold about 4.7 GB of information.
    You can burn files on a DVD-R disc using the Apple
    SuperDrive. DVD-R discs are not reusable; you can burn
    files on them only once.
    [1] Action item one is to acquire genuine quality media
    disc(s). [ to, ideally, accomplish burn verification ]
    If 100% media disc burn and verification were able to be
    accomplished by the OS X supplied applications Finder
    and Disk Utility then only limitations to overcome are:
    Finder's (improved standards adhering) write once only
    to media disc feature and Disk Utility's apple OS only
    media disc burned format limitation and maybe multi-
    session disc burning feature.
    [2] Action item two is to acquire genuine quality media
    disc burning software(s). [to accomplish burn media
    capacities and maximum standards adherences ]
    If fuller standards compatibility and media disc burn
    usage features are available then items one and two
    requirements seem to be met. And actions items three
    and four are no longer options of any material
    significance. That would be welcome.
    [3] Action item three is to optionally acquire an
    alternative media disc burning solution. [ to accomplish
    100% or nearest possible media burn quality and
    consistency ]
    [4] Action item four is to forego media disc burning
    (item three) in favour of external hard disk solution
    (which could be partitioned) to share datafiles among
    differing machines and operating systems. [ to resolve
    the media sharing challenge in the absence of
    satisfactory value media burning solution that meets
    quality, consistency and compatibility needs ]
    Hopefully .. this tale of media burning discovery does
    ignite some passion and interest among certain others of
    you who may be willing to share a little of your own
    enlightening discoveries in the industry of media disc
    burning and any Apple SuperDrive MATSHITA guidelines or
    guidance(s) that you have established .. in particular.

  • Dual Layer DVD media help

    Does anybody know what DVD +R or -R Dual Layer media is compatible with Macintosh (specifically, Dual 2.5 Ghz G5 running the Final Cut HD Studio.
    I tried Fujifilm DVD+R DL and DVD Studio Pro 4 did not recognize the disc when I tried to build/burn the disc. The Apple Store does not sell any Dual Layer DVD media and Best Buy only had the aforementioned media available for sale.
    What do the Hollywood studio use for their dual layer media?
    Thanks!

    Hi David,
    I authored a dual layer DVD a few months back and had no problems with Memorex DVD+R DL media. They came in 15 disc packs.
    I'm in Miami, so I can't say what the Hollywood studios are using for one-offs, but the dual layer DVDs you rent
    from BlockBuster or NetFlix aren't recordable DVD media discs. They're DVD-9 discs from a replication facility.
    Cheers and happy authoring,
    Jeff

  • DVD Drive Doesn't recognize Media Disc

    I have an Envy dv7. Product # B6B75AV. DVD drive hpBD MLT UJ260
    I have a program that will copy a dvd from the source, dvd drive #1, to the target same dvd drive #1.
    When it is done copying the disc it ejects the original and asks to have a writable media disc inserted. 
    When I insert the DVD  the drive doesn't recognize the blank dvd, keeps asking for it, and when I put it in, it spits back out saying to insert a writable disc.  I have used the blank DVD+R for burning other things so it should work.  I tired putting in 4 different blank discs to make sure the disc was ok.
    Is there anyway to find out for sure whether this DVD writer uses DVD+R or DVD-R?
    Any help will be appreciated.

  • Disc drive ejecting dvd media

    the drive in my Imac G5 2.1Ghz will not hold blank media disc in it they don't show in the finder i place them in to the computer slot drive less then a few minutes it ejects the disc. I have tried to rest the smu/pmu , the PRam , i even went as far to reset the nvram still the drive will not hold the blank media .It will however read pervious burnt dvd disc of the same carousel and pressed dvds.
    any thoughts of what other step i should try would be appreciated
    the Imac is running 10.4.11

    It's DUST, yup, dust.
    I was having the same problem no matter what type of media - movies would sometimes eject and I would put it back in a few times, then it would work.
    Anyway, solution, clean it. You can use air, but that is not as good as what I did.
    For $10.00 at best buy, you can buy this disk that has tiny cleaning brushes on it. Its called OptiDisc by memorex. At first it didn't play, and ejected of course, so, I put it back in and opened itunes, it's also an audio disc that will clean and set up audio and test it.
    I did this last night after buying some DL Verbatium DVD's that kept ejecting, then I tried -R same thing, after the cleaning section, takes less than 2 minutes, every time I put in a blank DVD I got the what would you like to do.
    It has nothing to do with the OS. I have a MB Pro with Tiger 10.4 as well as external HD with 3 partitions, with two bootable, one is 10.5.6 the other 10.5.8, before cleaning, all three OS'es ejected them, after cleaning it now works fine. Good for 30 uses and they recommend after ever 50 hours but since my macbook is one year old, I am thinking it will probably last for a long long time.
    Hope this helps you as like me, you probably thought you had to get it fixed and even with Apple care you would be without your mac for days.
    This fixed my problem and I bet it fixes a lot of peoples, especially dust, it does collect.
    Thanks!

  • Best Export Settings for DVD burning and Computer viewing

    Hello,
    I am trying to export a 1 hour video that I need to be compatible with standard DVD players as well as viewable on any computer.
    Original footage was shot with a Canon 5d Mark ii in 24fps.
    I have done all of my editing in Premiere Pro CS6. From there, I exported a high quality file to bring into Media Encoder (for trials of best output). My master file from Premiere was exported with the Preset MPEG2. The only thing I changed in the preset was VBR from 1 pass to 2 pass.. This gave me a 6.2 GB file.
    I then brought that file into Media Encoder where I have tried the following presets:
    MPEG2-DVD - Match Source Attributes
    MPEG2-DVD - NTSC 23.976fps Widescreen High Quality
    MPEG2 - HDTV 720p 23.976 High Quality
    MPEG2 - NTSC DV High Quality
    These settings have encountered various issues.. some have significant banding, but most importantly, none of them will play on my DVD player when I burn them to a disc.
    The discs I am using are Sony DVD-RW with a 4.7GB capacity.
    Where am I going wrong here? From what I've read, the format needs to be MPEG2 to be viewed on DVD... Sorry if I sound ignorant! This stuff is tricky..

    First off, don't export your timeline and then take the result to AME to re-encode, this is compressing your video twice and degrading quality (not to mention takes extra time and hard drive space). Always export direct from Premiere to Media Encoder. If you must use an "intermediate" file as part of your workflow, perhaps to archive a completed video that might later be exported to other formats, then use a lossless codec such as UT or Lagarith (free downloads).
    For DVDs, you MUST use "MPEG-2 DVD". Other forms of MPEG-2 are not appropriate, as the official DVD specification requires that the MPEG-2 file has certain attributes. Not recommended to use "Match Source" for ANY export, just choose an appropriate setting as needed.
    This should be correct for your application - MPEG-2 DVD > NTSC 23.976fps Widescreen High Quality
    If you want to encode a DVD file over 1 hour in length, then you will need to adjust the encoding bitrate so the resulting file will fit the disc. Rule of thumb is 560/minutes = bitrate, but you might round down the result a bit to allow for menu overhead and such, depending.
    Once you export the "MPEG-2 DVD" file, you can NOT simply burn that file to DVD media. That is only creating a DATA disc and it will not be playable in a DVD player (though a computer or PS3/PS4 may work since they can play most media files). To make a DVD that works in all DVD players (and meets the spec), it MUST be "authored" in a program like Adobe Encore. This compiles your content and menus and all that and then writes the result to the disc in certain way so that DVD players can read the disc. If you open any DVD on your computer, you will see a folder called "VIDEO_TS" and inside that there are .vob files and others. That is a proper DVD. And once you have a proper DVD, you can't simply copy the VIDEO_TS to another disc (as DATA), you must tell the burning software to create as a "VIDEO DVD" and not DATA, or it again won't be readable in a DVD player. Very picky spec, sorry.
    When using AME to export MPEG-2 DVD, it will create two files, audio and video (.m2v and .wav), you will then Import both of those into Encore together. Note that you CAN import other formats into Encore, such as .avi but Encore will then transcode that to the correct MPEG-2 format anyway, so best that you take charge and create the right media in the first place in AME before you get to Encore.
    EDIT: In AME, any time that your source is higher resolution than the destination, such as HD to DVD, you can check the "Max Render Quality" button in AME to provide the best downscale quality.
    EDIT 2: I see you're using DVD-RW media. That is fine for experimenting, but for delivery to clients always use good quality DVD-R or DVD+R media. DVD-RW may not have the best compatibility with players and costs more anyways. DVDs are so cheap now that I just proof to DVD-R and toss the bad ones, up to you.
    Thanks

  • I want to create a HD disc with my Adobe Premier Elements but I am getting low resolution.  When I go to share the DVD to disc the form only offers 8pixels at the bottom.  How do I burn this DVD in HD with higher number of pixels?

    I want to create a HD disc with my Adobe Premier Elements but I am getting low resolution.  When I go to share the DVD to disc the form only offers 8pixels at the bottom.  How do I burn this DVD in HD with higher number of pixels?  I have read other forums on burning HD DVD's but I do not see the option to turn the 8 pi into 40 pi the one forum recommended.  I want my DVD to be HD so I may sell these videos online for my business.  I can't sell them the low quality they are burning now.  Hopefully you can help me.  Thanks.

    desalvom
    Thank you for your reply.
    You cannot burn your high resolution video that you can view on your computer to an AVCHD on DVD disc
    that will replay through a regular DVD player. But players are marketed under a variety of names with
    different support opportunities. One manufacturer may call its product MultiMedia Player, media player, Blu-ray player,
    etc.The bottom line is the specifications for each of the players that are candidates for the playback of
    the AVCHD format on DVD disc or the format of interest.
    If you upload your HD (1920 x 1080) video to YouTube, YouTube converts the video to flash format, but it goes up as the HD video.
    But, beware. Look at the YouTube viewing setting when your uploaded video is playing back. The YouTube default is not
    HD. It might be 360p, 480p. If you have a 1080p video, then before the YouTube playback, you should be looking
    at the video with the YouTube 1080p HD setting for best viewing. That is a YouTube matter.
    Best results depend on you
    a. setting up the Premiere Elements project preset to match the properties of the source media. That means, if
    you have 1080p source, you (manually) or the project (automatically) set the project preset at
    NTSC
    DSLR
    1080p
    DSLR [email protected]
    or the PAL counterpart, depending on your region need.
    b. if you upload your video to YouTube using the Premiere Elements feature, there is a HD preset, but you cannot
    customize it.....if you need customization, then you can export your Timeline to a file...in this example
    Publish+Share
    Computer
    AVCHD
    with Presets = MP4 H.264 1920 x 1080p30 or PAL counterpart
    and then customize the preset under the Advanced Button/Video Tab of that preset. In increase quality, you might look to increase
    the Bitrate under Advanced Button/Video Tab settings - without compromising the file size.
    Then you would upload that file to YouTube at the YouTube web site.
    All of the above are factors that need looking into in order to determine the why for what you wrote
    I have published a shortened advertisement video to YouTube- say 5 minutes-
    and it is low quality
    Often SD video upscaled to HD can present poorly. But, you are dealing with a HD workflow so that should not be introduced into the matter. The setup of the project and
    the properties of the source video are important, but let us start with the above and rule in or out those considerations first.
    Thank you. As always, any clarification needed, please do not hesitate to ask.

  • Some CD and DVD media no longer works

    When custom burning CDs and DVDs, the quality of the media matters as much as the drive chosen. It has been found that spindle stored media, label stuck media, and ink written on media, and media burnt at the maximum speed can become unreadable a lot more than the alternative. After researching this topic thoroughly, I've come to the conclusion that following these basic steps in buying, burning, and storing discs will lengthen the life of media:
    1. Store media in jewelcases.
    2. When it is CD, make sure it is made by Verbatim, Kodak, Imation, Sony.
    3. When it is DVD make sure it is made by Verbatim, Ritek, or Taiyo-Yuden.
    4. Do not apply sticky labels. Don't write with markers on the disc. Use jewelcase inserts to organize contents of disc externally.
    5. Burn at less than maximum speed.
    6. Fit the criteria here:
    http://support.apple.com/kb/HT2446?viewlocale=en_US
    7. Use the format of ISO-9660, as opposed to UDF, or Joliet, when not burning standard audio, photo, or standard DVD movie discs. ISO-9660 is more compatible with both Mac and PC platforms.
    While not a permanent solution, it is better than the alternative of finding discs that simply won't burn, or getting media that gets stuck in your drive.
    Recommendations for media manufacturer here are based on lengthy research of various sites on the internet.

  • Can't burn .ISO image with k3b/brasero on DVD-RW disc.

    I don't understand what's going wrong here, so I hope someone can help me.
    I have created an .ISO image (of a video) using DVDstyler.
    (1) DVDstyler will burn it to a DVD-RW without any problems.
    (2) I can burn it from the command line (growisofs etc.)
    (3) I can burn it to a DVD-R from any application (DVDstyler, K3b, Brasero)
    K3B and Brasero will write data to a DVD-RW any without problems
    But, when I try to burn the dvd.iso to a DVD-RW disc with either k3b or Brasero, they fail with various  error messages.

    I hope this is enough to give some clues.  BTW, I have tried  forcing a re-format on the disc first from within the application, which reports success. It all used to work some months ago, but since I do not do this regularly, I can't identify exactly when the problem started.
    I would really appreciate some guidance.
    Many thanks in advance

    He already stated thet he is re-formated teh disk
    @myrlin
    as far as i can see, problem is with
    cdrecord: Data does not fit on current disk.
    try to reduce data for burning.

  • DVD data disc song order

    Is it possible to burn a DVD MP3 disc in itunes. Every time I select MP3 disc and insert a DVD it switches to data disc. I then end up with a disc of seemingly randomly organised tracks which is pretty useless when trying to play in my dvd player as I cant browse by album.

    If the footage was shot in NTSC and they want PAL, you'll need to convert. JES Deinterlacer is an excellent (and free) tool for that. Just export from iMovie, then convert to DV PAL.
    If you have Toast, make sure you select "DATA DISC" and "MAC & PC", then just drag the video files into the window. Remember that DV PAL is roughly 13 GB/h, so you can fit about 15 min max onto an SL DVD.

  • Cs5 export direct to dvd

    I cannot seem to have any luck exporting direct to DVD bypassing Encore. I export to media, tried several selections but no output selection to dvd.

    Hi,
    There is no way to directly export to a DVD from Premiere. You've got to use Encore.
    When exporting a file from the Export Settings dialog box for use in DVD or Blu-ray Disc creation, select the format appropriate for the target medium. For single-layer or dual-layer DVD, select MPEG2-DVD. For single-layer or dual-layer Blu-ray Disc, select either MPEG2 Blu-ray or H.264 Blu-ray.
    Thanks!

  • Question on reinstalling DVD media software on a Satellite A100-049

    When I first ran the System Restore on my Toshiba laptop it put these two on but I can see no way to reinstall them without restoring the entire drive back to when I first bought it. I still have WinDVD installed but have removed Ulead (I forget the exact name of the DVD Media software) and cannot now re-install it.
    Would Toshiba send me a proper installation CD for these?
    Thanks

    Thanks. I was thinking that.
    There's nothing wrong with the actual disc as far as I'm aware. There just appears to be no obvious menu when you run it from Windows. It restores perfectly fine. I wasn't sure if Toshiba would send me "normal" CDs for this software. I'm not after anything more than I get anyway.

  • Odd problems with reading DVD media [concluded]

    There is an odd problem I've encountered...(I'm not sure if its a bug with Arch Linux or Linux in general).
    Firstly, the details:
    * I've updated the systems (using "extra", "current", and "community" respositories). So its the current one (0.80 "Voodoo"). I'm NOT using "Unstable" respository.
    * I've already added the user to the "optical" and "storage" groups. So there's no problems in relations to permissions.
    * My fstab entries for the CD and DVD drives are default (I didn't touch them)...That is, "iso9660" and "udf" respectively.
    * My desktop environment is KDE 3.5.5...And I have changed the behaviour of the desktop icons such that DVD media, CD media, and USB devices will have an icon pop-up as soon as you plug them in.
    * I have "hal" loaded in the DAEMONS of /etc/rc.conf
    * I'm using 4 different Linux systems with the following DVD burners.
    => Pioneer DVR-108
    => Sony DW-Q120A
    => Hitachi-LG GCC-4240N (DVD-ROM/CD-burner combo)
    * There are three Sempron 2800+ (Socket 754, 1.6Ghz) boxes and the last one is on an IBM R40 ThinkPad, and I know you can't read DVD-R media on that. But it should be able to read DVD+R media without issue.
    * Two of the Semprons are running Arch, as well as the ThinkPad. The final Sempron box is running Ubuntu 6.06.1
    * When I installed K3b I did: pacman -S k3b dvd+rw-tools
    * All the DVD media is Verbatim DataLifePlus ones.
    Here's what I've done...
    I've burnt two DVD media (they're just video files from last year's Blender 2006 conference thing, so its legal stuff).
    One is a DVD+R and the other is DVD-R media. Both were done on a Windows 2000 Pro SP4 box using Nero 6.6.1.4
    What's the problem?
    Well, KDE in the Arch Linux boxes doesn't recognise the media!...There is no DVD icon that automatically pops up on any of the Arch Linux boxes!
    When I run dmesg on the Arch boxes, the only relevant info I get is:
    ISO 9660 Extensions: Microsoft Joliet Level 3
    ISOFS: changing to secondary root
    Now if I re-insert these DVD media onto an Ubuntu 6.06.1 LTS box...The DVD+R works perfectly! While the DVD-R does not.
    When I run dmesg on this box, I get the following:
    [17179654.808000] hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplet e Error }

    If I re-burn the data onto a DVD+RW, Arch and Ubuntu immediately sees it, and KDE (or Gnome in Ubuntu), will have a DVD icon popping up! I can view the video clips without issue!
    Now here's the really odd part...
    When I load up K3b on either Arch OR Ubuntu, they recognise all DVD media! (As in, they can read the media disc information!)...Tools => DiskInfo
    If I click on the PIONEER - DVD-RW DVR-108 on the tree menu on the left side in K3b, (to view the contents of the DVD-R or DVD+R media), it can't read and pops up an error message informing about a read problem. It suggests I try dmesg|tail to see what's wrong.
    When I do that, I get...
    # dmesg|tail
    grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
    UDF-fs: No partition found (1)

    grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
    UDF-fs: No partition found (1)
    I repeat the same procedure on DVD+RW, and it works perfectly!
    Should I use another burning application instead of Nero on the Windows box?
    Could it be the way I burn things?
    (Some DVD+R and DVD-R are burnt with multisession while others aren't.)
    Has anyone else experienced similar issues?
    What are your "workarounds" or fixes?

    It *should* work...But they don't.
    I tried this...
    mount -t auto /dev/dvd /mnt/dvd
    I get this...
    mount: block device /dev/dvd is write-protected, mounting read-only
    mount: wrong fs type, bad option, bad superblock on /dev/dvd,
    missing codepage or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so
    I then do dmesg|tail
    grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
    UDF-fs: No partition found (1)
    If I try this...
    mount -t iso9660 /dev/dvd /mnt/dvd
    I get this...
    mount: block device /dev/dvd is write-protected, mounting read-only
    mount: wrong fs type, bad option, bad superblock on /dev/dvd,
    missing codepage or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so
    I then do dmesg|tail
    Unable to identify CD-ROM format.
    If I stick in a DVD-R that is burnt in one go without multisession, I get this in the dmesg
    UDF-fs: Partition marked readonly; forcing readonly mount
    UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'SW', timestamp 2006/11/07 19:37 (1000)
    It reads this disc perfectly and KDE pops up a DVD icon.
    I'm scratching my head as I'm not sure what is the problem.
    Could it be hal or the way the DVD media was formatted?

  • How do I burn a DVD R disc with Windows Movie Maker?  It indicates disc error on my DVD player.  Someone thought it had something to do with Itunes?  I reloaded Itunes 1 month ago and had no problem creating this disc then.  Help

    I have made several DVD+R discs in the past using Windows Live Movie Maker sucessfully.  I made one about one month ago for my son's b-day.  I am using the same discs as I had then.  When I tried to burn the disc, it indicates that it is burning, however, when I insert it into the DVD player at home on our TV (like I"ve always done), it indicates disc error.  Someone mentioned that the burner goes out every now and then when Itunes is uploaded?  When I burn the disc, I can pull it up on my home and work computers, so I know that it is there.

    Yes, you can distribute a burned disk of the project to those who can create duplicate disks.  Or create a disk image of the iDVD project using the File ➙ Save as Disk Image menu option.
    Then you can distribute the disk image to those who will burn the disks.  For PCs you'll have to convert the .dmg file to a .iso file so they can burn it.  This website describer how: Mac Help - Convert and Burn Mac .dmg or .img to .iso Windows PC-Compatible Disk Image
    Suggest to them to burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
    It would be prudent to rest your optical drive for about 30 minutes after burning 3 disks in a row. That will give the laser time to cool down before you start another batch.
