Mac Burnt DVD-R Same As PC?

Hi. I have a beginner's question...
If I burn a data DVD-R on my iMac, will it be exactly the same as a DVD-R burnt on a PC? Or will it be in some weird Mac format? I've done some tests, and the file system of a Mac burnt DVD-R, and a PC burnt DVD-R, is the same. They both use UDF file systems. Is that all there is to it?

The default is an ISO9660 format disk with Joliet (Windows), RockRidge (UNIX/Linux), and HFS (Mac) extensions. You will be able to read it on anything that reads DVD-R disks.
Generally, Windows burning software only includes the Joliet extensions.
Joliet extensions permit Windows-style long filenames. RockRidge extenstions provide UNIX-style long filenames, file permissions, and file ownership data, and HFS extensions provide file type and file creator information.
The ISO standard specifies that if a particular driver doesn't understand some extension, that the extension should be ignored gracefully. The presence of a particular extension is never required for the data to be readable.

Burnt DVDs no longer recognised on my mac

Recently, my internal drive is acting up. It no longer recognises burnt DVDS. they don't show on the screen and then they just self eject.
Also, when I insert a burnt CD, it is not always recognised on the desktop.
I'm using 10.7.5. Any suggestions?

Hi imnokid2,
Welcome to the Support Communities! The resource below will explain how to check your optical drive if it is not recognizing your DVDs. Does it have any problem reading/playing store-bought DVDs? What software are you using to create the DVDs?
Get help with the slot-loading SuperDrive on your Mac computer - Apple Support
http://support.apple.com/en-gb/HT201788
Accepts discs but they don't mount or are automatically ejected
Reset the System Management Controller (SMC).
Ensure your drive can read the specific type of disc being used. The System Profiler or System Information may provide additional information regarding what media your computer supports.OS X Lion v10.7 and later: Click the Apple () menu and then hold down the Option key. Choose System Information from the menu.
If the disc continues to not be recognized, contact Apple or an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store.
I hope this information helps ....

Burnt DVD's appearing as blank CD's

Hi,
New Macpro is reading some DVD's as blank CD's, hence archived material is not available. This problem is consistent on any particular disc yet does not occur to all discs of the same type and burnt on the same (not the Macpro)machine under identical conditions. The offending discs can be read on other machines no problem. Firmware is up to date.
Any suggestions? Anyone else experienced this?
Thanks,
Glenn.
G4 dual867 & 1.67PBOOK & G5 2.5quad & MacMini(Intel 166Duo) & Macpro 2.66Ghz Mac OS X (10.4.9) etc

Hi,
I'm having the same problem.
My Mac Pro is a week old and it won't read Verbatim Double Layer DVD+R discs. I have quite a bit of work that has been backed to these discs that were burned on my old G5 quad.
All i get when i put them in the Mac Pro is a blank disc with "CDR" icon on the desktop.
Strangely, i can access the disc using an imac (also a week old) over the network.
It'd be great to find a solution as its getting a little inconvenient have to access the disc over the network.
cheers

MacBook will not play burnt DVDs?

Hi, not sure if anyone posted this topic already so sorry in advance, but i wanted to know why won't my macbook play burnt DVDs. The DVDs worked fine on my dvd player, my other PC etc. When i load the burnt DVD into my macbook it wouldnt recognize the disk and when i open the dvd platey and hit play it would say something like please enter a readable disk. Any suggestions would be great. Thanks.
Black MacBook 2.0GHZ 1GB RAM 80GB HD; 5TH GEN Black iPod Video Mac OS X (10.4.7)

I have the same problem with my MacBook 2.0 GHz.
The DVDs in question are DVD-RWs burnt with Pioneer DVR-520H, they work fine on my iMac G4 (DVD-Player & VLC) but when I insert the DVD in my MacBook the DVD-Player doesn't recognize the "media type" and VLC player gives me an error log like this :
vcd: search for kIOCDMediaClass came up empty
vcd: failed to get the TOC
vcd: no movie tracks found
access_file: file /dev/rdisk1 is empty, aborting
cdda: search for kIOCDMediaClass came up empty
cdda: failed to get the TOC
cdda: no audio tracks found
main: no suitable access module for `dvdnav:///dev/rdisk1'
macosx: Error: Unable to open 'dvdnav:///dev/rdisk1'
The interesting thing is that the DVD shows fine on my MacBook's desktop, I can open it and when I copy the VIDEO_TS -folder on my hard disk I can play it with no problems with either DVD-player or VLC.
So my MacBook can read the disc, it just can't play it - what could be causing this problem?
I have been suggested trying DVD-Rs instead of DVD-RWs, but I don't think this solves the problem, I wanna be able to play RWs too if they work fine on my iMac G4.
The DVDs have also been tested on PowerBook G4 (works fine) and Intel iMac (the same problem as with my MacBook = doesn't work). The DVDs aren't copied, they have material recorded from TV using the Pioneer DVR-520H (the same machine used for burning the DVDs) on them.
I'm able to play normal, rented or bought DVDs on my MacBook. Both machines are running the latest Tiger OS.
Thank you in advance.

I can watch my custom DVD in iDVD 7 preview but burnt dvd plays back black with only the audio

I can watch my custom created DVD in iDVD 7 preview but once the disc is burnt and I play it back in DVD Player, the screen is black with only the audio playing back. I have tried using three different blank DVD manufactures.

Hi
Most probably depends on what movie codec You feed iDVD. May be You find any clue here.
DVD quality
1. iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1) and iDVD 6 has the two last ones
• Professional Quality
(movies + menus up to 120 min.) - BEST (but not always for short movies e.g. up to 45 minutes in total)
• Best Performances
(movies + menus less than 60 min.) - High quality on final DVD (Can be best for short movies)
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6)
(movies + menus up to 120 min.) - slightly lower quality than above
About double on DL DVDs.
2. Video from
• FCE/P - Export out as full quality QuickTime.mov (not self-containing, no conversion)
• iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos and the Ken Burns effect NOT is used. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
• iMovie’08 or 09 or 11 are not meant to go to iDVD. Go via Media Browser or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly e.g. x4 or x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application when burning from a DiskImage.
4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
use an external one as scratch disk (if it is not start-up disc). For SD-Video - if HD-material is used I guess that 4 to 5 times more would do.
5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
6. I use DVD-R (no +R or +/-RW) - DVD-R play’s on more and older DVD-Players
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
(I use JES_Deinterlacer to keep frame per sec. same from editing to the Video-DVD result.)
8. Don’t burn more than three DVDs at a time - but let the laser cool off for a while before next batch.
iDVD quality also depends on.
• DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
deliver anything better that this.
HD-DVD was a short-lived standard and it was only a few Toshiba DVD-players that could playback.
These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-Player.
Blu-Ray / BD can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
_ Roxio Toast™ 10 Pro incl. BD-component
_ BD disks and burner if full length movies are to be stored
_ BD-Player or PlayStation3 - to be able to playback
The BD-encoded DVDs can be play-backed IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
• HOW much free space is there on Your internal (start-up) hard disk. Go for approx. 25Gb.
less than 5Gb and Your result will most probably not play.
• How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
• Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
• Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera record in = 100% to iDVD
• What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
Convert to .aiff first and use this in movie project
• What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
(If You need to change to do a NTSC DVD from PAL material let JES_Deinterlacer_3.2.2 do the conversion)
(Dropping a PAL movie into a NTSC iDVD project
(US) NTSC DVDs most often are playable in EU
(EU) PAL DVDs most often needs to be converted to play in US
UNLESS. They are play-backed by a Mac - then You need not to care
• What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
• How You encode and burn it. Two settings prior iDVD’08 or 09
Pro Quality (only in iDVD 08 & 09)
Best / High Quality (not always - most often not)
Best / High Performances (most often my choice before Pro Quality)
1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
(x4 by some and may be even better)
2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
Region codes.
iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
DVD Studio pro can set Region codes.
1 = US
2 = EU

What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk
• No other programs running in BackGround e.g. Energy-Saver
• Don’t let HD spin down or be turned off (in Energy-Save)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show

Burnt dvd's

Hello, I just noticed that I am unable to mount burnt dvd's
on my emac. This includes dvds from idvd, data dvd's, and dvd's thru toast. I am able to mount these on a dvd on a pc, or a dvd player, just not on my emac. I have been using the same dvd -r from day 1.
I am using the latest tiger but I have not installed 10.4.7
yet. I also have tried disc repair, still nothing.
any ideas?

I am having this same problem on a Power Mac G5, which I just upgraded to 10.4.7 a day or two ago. I know I wasn't having this problem with 10.4.6, and I'm certain there's nothing wrong with the discs. Burned CD-ROMs and regular DVDs work fine, but DVD-R will not mount.

My MacBook Pro does not read burnt DVD

Hi guys,
Does anyone of you alredy encountered the following problem with your optical drive (Matshita DVD-R UJ 857):
- Perfect CD reading/recording
- Perfect original DVD reading
- Perfect DVD burning
- No or almost no burnt DVD reading.
This is becoming nasty since you back up your stuff on a blank DVD (verbatim DVD-R) but cant read them back...
Anyone out there that has the same pityful problem?
Let me know,
.M

I too am having this problem. I spoke with Apple Support and they basically said "if it reads the DVDs we provide then it's not broken". What a joke.
The DVDs I am having problems with are all from commercial software that I purchased, but they are not pressed discs. They are DVD-R or DVD+R (not sure which). The discs do not read on my 15" MBP, but read just fine on my 15" PB and on my desktop Windows system. To me it seems that the new SuperDrive is not so super after all.
Hopefully Apple will hear from enough of us that this is a problem, and then maybe they will actually do something to fix it.
Cheers

Burnt IDVD project, but unable to reburn the burnt dvd?

Ive finished an idvd project burnt it to a dvd, and that works fine which is great, but nieve me deleted the idvd project on the computer thinking i would be able to just burn copies off the one dvd cd copy ive got, but it is appearing impossible? It just burns a bunch of useless files that are not viewable. Is this normal? If not what format changes do i have to make to be able burn a burnt dvd?

Yes, you are correct that you can use third-party software to rip content from a burned DVD disk. You can use Handbrake, Ripit or something like that if you need to re-edit the content of the burned DVD, but you will take a quality loss as the data has to be uncompressed and then recompressed to burn a new DVD.
This person just wanted to know how to burn another DVD of the same; therefore, we gave instructions for how to burn it from the previously burned DVD disk. There is no loss of quality this way.

Superdrive Won't Read Burnt DVD's

Hi all,
Recently my superdrive has started acting up and will not read any burnt DVD's (data, movies,etc.). It will read burnt CD's, music CD's and "Studio" Movie DVD's, it will even read and recognize blank DVD's and allow me to burn but if I eject the disk after burning it will not mount. All of the disks I have tried were burnt by this drive and used to work at one point or another. I have also tried a disk created on a friends Mac and it still doesn't work. Seems that the drive will do everything but read burnt DVD's. Anyone else encounter this problem? Solutions?
Thanks,
J.

I just burned some DVD+R DL and had no problems burning or reading. The System Profiler shows the DVDs that it can handle. My list under Disc Burning is: DVD-Write: -R, -RW, +R, +RW, +R DL. Under <Reads DVD> all it says it <Yes>. I think that's a little succinct. But, because it can burn +R DL, it must be safe to assume that it can also read them. I used Disk Utility and made disk images. (Great little guys.) The media was Memorex. Ray

Avi format burnt dvd's

hi there guys please help i desperately need it.
i recently acquired loads of burnt dvds of my mate and there all avi's and ive tried to rip them of handbrake but it doesnt recognise the cd.
is there anything that i can do?...do i need to convert the avi format?...please help.

if they're AVI just open the disc in finder and drag them to where you want them. you should be able to watch them, sometimes AVI's won't play correctly so you would have to get the DIVX codec if that is the case.

How can multiple Mac users have the same iTunes?

I have a MacBook, and my wife and I have separate accounts on it. It's easier that way for separate Facebook accounts, email, etc. However, it's complicated when it comes to iTunes and applications. We both want to use the same iTunes library. We have iTunes Match, but I'd rather not re-download my entire library when it's already on my computer just so we both have access to it. I tried following the directions at this article, but it didn't work. So, how can both my wife and I, from different accounts on the same Mac (and using the same Apple ID) access the same iTunes library and have any changes reflected on both accounts?

Obviously, if you just need to copy those iTunes folders, you don't need the ability to write; just the ability to read, which you already have.
Besides, the /Users/Shared folder is indeed an excellent location for a shared iTunes library; I hadn't yet considered that. Ignore all the above instructions. First, make sure your two iTunes libraries are in sync. Use an external hard drive (or mess with permissions) to do what copying you need to. Then go into iTunes and iTunes>Preferences...>Advanced and change the iTunes Media folder location to /Users/Shared. All of your iTunes content should be copied (or moved) into /Users/Shared.
After that, do the same thing in the other account, and both your iTunes libraries will now be pointed to the same location.

2 Mac's sharing the same itunes library?

2 Mac’s sharing the same itunes library?
I would like to use the same existing itunes music folder I have on a external drive, connected to one of my machines?
I can share without any problem the drive from my laptop and can share/view the other machines itunes music through itunes on my laptop, but can not set the music folder on my laptops Itunes to be the same as on the machine that the external drive is connected to.
I have heard and seen this operation before but how do I do it ?

You lost me on which machine is which and where the library is stored. If the library is on an external drive connected to Computer 1 and you want to access it on Computer 2 then:
1. Connect to computer 1 using the Finder on Computer 2 and mount the external drive
2. Open iTunes on Computer 2
3. Select iTunes -> Preferences
4. Select the Advanced tab
5. Select Change next to iTunes Music Folder Location
6. Navigate to the folder where the music is stored.
7. Quit iTunes
8. Open iTunes with the OPTION key held down.
9. When prompted navigate to the Library file on Computer 1.
That should do it. As always, back up the Library file before you start this process. I would also recommend you back it up regularly as if you have a network issue while accessing the library file remotely, it could corrupt it.

We are two people using three difrent Macs, 1 Iphone and 1 Ipad with separate USERS on each Mac but sharing the same Apple ID: xxxxxx

Do we have to set up a diffrent Apple ID for each other?
Sometime ago I added my friends E mail (yyyyy) to the main Apple ID (xxxx) as for using his E mail account (to separate our e mail accounts, and it's working ok) but now when I try to create a new apple ID whith the same friend's e mail (yyyyyy) it says that his mail (yyyyy) is already an apple ID when the Apple ID is really my E mail (xxxxx)... any clue?
Thanks

I believe because you migrated from a Nokia to an iPhone you need to register the Bn phone number with your Apple ID so it can be used for iMessage. The Pn number seems to be the only one registered
Go here > https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/
Manage your Apple ID and see if that does the trick
Hope that helps

How do I share files between computers (mac's) on the same wireless network?

Turn on File Sharing in System Preferences - Sharing, then you should be able to see them in the other Macs' Finder sidebars (under Shared). Click on them, click Connect As, and log in with the user credentials you're sharing from.
