DVD burner not reaching maximum write speed

I have a PowerMac G4, and have purchased an internal PIONEER DVD-RW DVR-112D. After contacting the manufacturer and discovering what media to use, all fingers point towards VERBATIM. The drive writes DVD's at 18x speed. I have purchased 16x DVD-R media from Verbatim.
I have NEVER been able to reach a write speed ABOVE 8x! What is wrong? Anyone else have this issue??

Older Macs, such as the G4 quicksilver, were designed when the fastest DVD drives were only 2X, and use a slow ATA bus for the optical drive. The only way to get more than 8X is to use a faster bus for the DVD drive, such as one of the other ATA busses in a G4 MDD, or a PCI controller card. If you do that, though, the optical drive may not be bootable, and the Eject key may not work.
My previous Mac was a G4 Quicksilver, upgraded with a Pioneer 110 drive (16X). It would not burn faster than 8x. The Mac Pro with a Pioneer 112 will burn at 16X. With a Pioneer 115 it will burn at 20X (with Verbatim DVD-R 16X media).

DVD burn doesn't offer correct speed

I have an iMac iSight (PowerMac12,1 PowerPC G5) with Matshita DVD-R UJ-846 SuperDrive. Mac OS X 10.4.8. According to the Tech Spec this iMac writes DVD-R and DVD+R discs at up to 8x speed.
If I use DVD-R media, and try to write using a burn folder, Finder says the maximum speed is 2x. Toast Titanium 5.2.3 also says the maximum burn speed is 2x, it correctly reports the disk size as 4.something GB, and offers Simulation mode burn.
If I use DVD+R media, and try to write using a burn folder, Finder says the maximum speed is 8x. Toast Titanium 5.2.3 also says the maximum burn speed is 8x, it incorrectly reports the disk size as 8 GB, and does not offers Simulation mode burn.
What on earth is going on?
I appreciate that Toast is not an Apple product, but I expect Toast is only reporting what Apple tells it, and similar faults appear in the Finder response.
Does burning from Finder verify the disk, because at the end of the process, there in no window visible saying that verification was successful?
(Note this does not seem to be related to the fault on SuperDrives relating to High-Speed media (Apple article 86130), because my drive is not a Pioneer drive).
iMac iSight G5 Mac OS X (10.4.8)

Note the phrase "up to". The maximum burning speed may be less than that specified on the disk blank, especially if the discs are faster than those available when the drive was manufactured. The drive make, model, and firmware version of the drive, and the brand of disc, may limit the speed to a lower value than that specified for the drive or the disc. For example, the first Quicksilver superdrive would burn 2X DVDs at 2X, but would only burn 4X DVDs (which didn't exist when the drive was made) at 1X. Try different brands of discs. I have good luck with Verbatim DVD-R. The newer Pioneer drives seem to be able to burn discs at their rated speed.
I don't know why Toast would report the wrong disc size. When using Finder's burn folders, you can click the small round button at the lower-right to see the disc size and space used. Does it show the correct size for the DVD+R discs? Are you sure they are not DVD+R DL discs, which are larger?
The Finder does verify discs it burns. If you look at the progress bar, you will see it change from "Writing" to "Verifying". If there is a verify error, it will eject the disc, rather than mount it, when finished. It will also display an error window. If the verify is successful, it will mount the disc, but not display a window. Disk Utility gives you a choice of what to do when the burn is complete, and always displays a window indicating success or failure.

DVD burner not recognizing DVDs

I've had a mini for quite some time now, and recently in the past few weeks I've had a strange problem where it no longer recognizes burnable/burned DVDs. CDs work fine, retail DVDs on movies work fine, but I am unable to access any of the things I've burned myself.
I've tried 3 of the types of burnable DVDs, and have even dug up some of my old DVDs I burned myself on this computer and they all do not mount. I've checked the system info, and the drive is still being detected as a DVD burner, so I am at a complete loss as to what could be causing this.
Any help would be greatly appreciated

I'm having exactly the same problem as this.
The last discs that I burned would have been in October/November, and after that I noticed that the Mac would no longer recognise burned DVD's.
As I need to burn some more discs I've been testing in the past few days and can confirm:
1. Will not read from burned DVD-R
2. Will not recognize blank DVD-R
3. Will recognize blank DVD-RW, but will not burn to them
I'm now searching around to see if it's a hardware or a firmware problem.
The data on the drive from System Profiler is as follows:
MATSHITA DVD-R UJ-835F:
Firmware Revision: GGND
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No
Any ideas anyone?
Thanks in advance.

External DVD burner not working

I have LITE-ON DVDRW SOHW-1633S DVD burner attached to my Mac via USB.
When I turn burner on, Mac OS successfully detects it and even ask me to mount blank dvd to my desktop. Also I see burner in Disk Utility as well as in the list of available burners in Toast 7. I can even open and close tray and write CDs, BUT not DVDs. There is some error happening in Toast or any other soft when I trying to burn dvd disk.
Also, I just noticed that in System Profiler in Disc Burning section there is information that Burn support is unsupported.
Is my burner unsupported by Mac OS X and I will not be able to write DVD disks with it?

Hi Sabanin,
don't panic. Download and install this: Patchburn
This should solve your problem.

HP DVD burner not compatible?

I recently purchased the HP Dvd Writer 635i from someone on ebay who said it is mac compatible. HP however, says it is not mac compatible (as I recently found out). My computer recognizes it as a reader, but not a writable drive!!!
Do you know of any place I could get a 3rd party driver for it, or any other way I can get this drive to work? I do not have a copy of Toast, but it seems that it's a hardware/driver problem more than anything...?
I run OS 10.3.9 on my 400mhz gigabit ethernet G4
Thanks!

What do you mean by bootable?
It reads cds & DVD + & - R discs well... it just won't write
Apple System Profiler says this:

DVD burner not recognized in Leopard by iDVD 7.0.1

Not exactly the same problem I found in my searches, so made a new topic.
Setup: G4 tower, dual Giga Design 1.8 GHZ, 1.5 MB RAM, Pioneer 109 burner.
System Profiler shows ability to burner everything including +r DL.
I had to use a 3rd party hack to get iMovie 7.1 installed. Leopard did not recognize my 1.8 processor as legitimate. It would recognize it if downgraded to 1.7 GHZ, but I chose not to do so. iMovie 7.1 (iLife 08) now launches and works, but I used iMovie HD to make this project.
1. I have burned other DVDs in Leopard with this DVD burner successfully, including a usable (proven) backup of my Tiger and Leopard DVDs, both DL.
2. I have over 100 GB space available on my Startup drive as well as 80 GB on another internal drive that is storing the iMovie project. The imovie project in question is 15 GB.
3. After creating the project in iMovie HD, I exported ("shared") to iDVD 7.0.1, chose a built-in theme and started the burn process. All was going well, so I went to bed. G4 set never to sleep for this project.
4. Next AM found that "error - .... disk not burned due to burner not recognized (error xxxxx). Didn't get the exact error number, but the iDVD project, when saved to Desktop was only 137 MB. The iMovie HD project is 15 GB, so iDVD should have created a project about 3 + GB.
5. Have NOT tried Apple Hardware test. Doesn't make sense to do so when the burner works fine in Leopard for other projects.
Is this problem due to iDVD 7.0.1 failing to be compatible with my G4 configuration like iMovie 7.1? Got no warning when installing or launching iDVD from iLife 08.
Any suggestions? I hope I've given enough useful info.
Incidentally, I'm not in a corner, as I copied the iMovie Hd project to a fW drive, and then used iDVD 7.0.1 on my MB Core Duo to render and burn it. Just want to find out what the problem is with my G4.

I'll try that. It may work as it is not iDVD making the determination if the optical drive is "qualified" but DU. As I said in my original post, I have burned DVDs in this internal burner using Leopard and a Finder Burn Folder. It is only iDVD that is between me and success.
I did manage to get the iMovie HD project burned using iDVD 7 on my Intel iMac. I will try editing another iMovie HD project, exporting to iDVD7, and saving as a disk image to a FW drive. I will report back the results, but it may be a day or two before that happens.
I should also probably try the same routine that failed on the chance that it was just a fluke.

New DVD burner not working w/iTunes

Okay, I've been working on this and digging through these forums for awhile now. I'm still stumped. So here we go:
I had a new DVD burner installed. I'm using Nero software which works fine for DVD, data, etc. However, iTunes gives me the "disc burner or software not found" message if I try to burn a disc from iTunes.
I have completely uninstalled and reinstalled iTunes (yes, latest version) twice now. No go.
In edit>preferences>advanced>burning CD burner: still shows the old CD-RW.
iTunes will recognize and play prerecorded CDs and ask if I want to import them.
In help>diagnostics>CD/DVD drive tests, after putting in a prerecorded CD as requested: Optical drive detected IS the correct device (D: ASUS DRW-1814BL) BUT I get a red dot with "no audio CD found" yet the songs are showing in the device window (in actual iTunes behind the diagnostic window).

DVD burning not working after upgrading to 10.5.1

Hi,
I just purchased a macbook and found that dvd burning stopped working after upgrading to mac os 10.5.1. I went back to 10.5 and now it works without problems. Since so far I haven't experience problems with 10.5, I will continue using it.
Anyway, I just wanted to let other users know about this problem. I didn't find any references about it in the forum.
Best wishes,
Manuel

Hi,
I just got DVD burning to work under 10.5.1. I had originally formatted the OS-X partition as "case sensitive". Today I reformatted the partition as a regular Mac-os journaled partition, re-installed leopard and the upgrade, and now DVD burning works fine. I am not 100% sure, but it seems that using the case sensitive format caused the problem.

DVD Burner not Recording

Anyone have issues with their iDVD or Studio Pro 3 software not burning? My iDVD burn icon won't work at all and in Pro 3 the icon/burn reads when you click it, but says "Formatting Successful" and doesn;t burn the disk...can't even get past that message...anyone got some advice? I Just bought a new Sony DVD burner (that I don't think I needed) so I can rule out the DVD burner. Seems like a software/settings issue now.........

DVD Burner shows up in Roxio. Now my iMovie won't export the MPEG2's. Says it can't be export due to unknown error. Pro says Formatting Successful as soon as I clivk the Burn icon.
All this happened after I was working on a wedding video. She gave me hispanic cd's that had video clips on them. After that, It hasn't burned a DVD since. I've verified permissions, corrected permissions, erased my hard disk and re-loaded, but nothing is working. I still get the same software errors in Imovie, iDVD, and Pro. Now, this chick is ready to sue me and need HELLLLPPPP!!!!!!!!!!!!!!!!!

Eternal DVD burner not function properly in Tiger!

I have a LG external dvd burner...everything worked great with my burner (10.3.9 <) prior to installing Tiger and it's updates.
My burner is having trouble in Tiger reading previous burned discs and transfering them over to my emac...also burning with Toast (v7) is now a problem...most burns do not finish.
I have now gone back to 10.3.9 and the burner works normal!
What is going on in Tiger and my burner?
(ps. I use firewire with my burner, and I had installed Tiger with cd discs using my emac cdrom drive.)
Message was edited by: fivealex

The last version of Tiger I tried was 10.4.3...what would be different in using 10.4.4 that it would help me?
Alex.
Why don't you update Tiger and see if that helps.

DVD Burner not found

I have recently installed a new DVD burner on my PC however when I tried to burn a DVD from Premier Elements it states that the burner is not found.
I have however been able to burn a disc when using AVCHD as it finds the burner.
The drop down for the find burner location is alos blank and not letting me find the drive.
Does anyone have any suggestions as top what I can do to get the dvd recognised.

endfates
This is now the 4th old post (this time only 1 year old instead of 3 to 4 like the others) in which you are sharing the same generalized report on what worked for you with a burner recognition problem. In each of your other threads that I am finding, I am asking for the following same supplemental information from you, information which I feel is important to your shared content. So, I repeat
endfates
What version of Premiere Elements are you working with and on what computer operating system is it running?
With what type of burner are you working where you had this burner not recognized issue - Blu-ray/DVD/CD or just DVD/CD?
What specific video codecs did you find it necessary to install beyond what was provided for by the program, QuickTime, Windows Media Player,
and the usual assortment of players?
Besides "burner not recognized", did you have any "media not present" issues as well?
This information would be important since there is a 4 year gap between since the last entry in this thread (2010) and your post in this thread
tonight (2014).
Thank you.
ATR
Again, I point out that there are negative as well as positive aspects to the try this and try that "codecs". That is why I feel the requested information is important to the serial generalized messages that you are posting one after the other tonight in 1 to 4 year old threads.

DVD Burner not working in Mac Mini

My mac mini (running OSX 10.7.5) all of a sudden stopped burning/reading DVDs, however CD burning and reading still works.
I ran my system's disk utility and corrected some problems and tried again to no avail. I tried a previously burned DVD which did not work either. However, after trying several DVDs, I got the burner to work (or at least it appeared to as it went thru the usual messages of recording my iDVD movie, but when the recording message showed DONE, the screen appeared to freeze there (typically, at this point, I usually get a message that asks if I want to burn another) --I was able to hit cancel to exit the program. Anyways, the DVD did not burn. At this point on the plus side, I can now read my previously burned DVD... so I tried again to burn my iDVD Movie again but it just spits out after 15-30 seconds.
I saw on some boards that I should try cleaning the burner? Do I have to take my system apart to do this? Do I use a cleaning disk? If this is the case, will my DVD acknowledge it if it isn't working? Or do I just spray compressed air into its slot?
Any help would be greatly appreciated as this is for a job that I need to get out.
Thanks so much!

Yes use a CD/DVD cleaning disk

It could be that the burning laser died. Different lasers are used for CD and DVD burning

Lacie DVD Burner not working on my G5

I just got my first external DVD burner--LaCie 16x External FireWire and USB 2.0 Dual Layer DVD Burner in d2 Design (Mfr# 300978) selling for $140 in most places--and I’m having all kinds trouble. DVDs and CDs not mounting seems to be the biggest problem. I bought one last week and it worked erratically from the get-go—but it burned great discs.
So I exchanged it today for another of the same model. It worked well for an hour or so and then it began having problems mounting DVDs. Then I burned 4 DVDs on it and 2 were lemons. Also, it make a unhealthy-sounding squeaky noise when it was burning. And now it won’t mount any DVDs.
I’m I missing something here? I’m running 10.3.9. I have a 1.6 ghz single processor G5. Is there a make and model that’s now all the rage with you guys out there?
Thanks!

1. There is a LaCie DVD D2 updater at the LaCie support site.
2. They are VERY media fussy - try Verbatim media, if that works the media you are using is being rejected - the LaCie's have a wealth of meaningless error messages when they are upset including "unstable firewire connection" and various "medium sense errors", and they all boil down to it hates the media you are using.
Only Verbatim DL DVD+R work so far - none of the others will, period. Ritek, Fuji, etc.

DVD Player not playing at correct speed

I have the 2011 iMac. I have Apple Care, etc, still in full warranty. Other than this, it is perfectly functional. When I play a DVD it does not play at normal speed. It isn't 2X speed either, I have checked everything, the problem is that it plays at around 1.25 - 1.5 speed. It's not REALLY noticeable, but it does become a little hard to listen to after a while, since the sound obviously gets distorted. I have checked with multiple DVDs, the one it's mainly noticeable on is Oblivion, came out barely two days ago.
Thankyou for your help

Bring it in for service. Ask them to check for an updated firmware for the drive.
