Idvd 4 QT 7.1.3 buffer underrun

I've burnt many DVDs using idvd 4 in OSX 10.3.9, but recently I started getting buffer under run messages, very long burn times and no success. I've followed a number of discussion threads, clearing out hard drive space, turning off sleep etc. Nothings worked. Found the thread that mentioned the possibility of a problem with Quicktime upgrades. I have QT 7.1.3
Basically, did anyone reinstall QT 7.04 or earlier and have success?? Is there any risk with this? I could purchase iLife 6 - but I don't know if that will work. I been told I can't go to OSX 10.4 as I'm running Final Cut Pro 3.
Did anyone find a fix?
Any suggestions would be greatly appreciated.
Cheers,
Ashley

Thankyou Michel.
My project is two Final Cut pro movies - 45 minutes in total, 13 chapters in segment (30 mins), none in the other (15mins)
and a slide show of 99 images - no transitions.
I have burnt very similar projects, say 200 times successfully, until very recently.
I can still burn data CD's and DVD's.
I have two external harddrives - I'm not burning directly from them at the moment, I thought it might be a problem? Sounds like I should change my setup - currently I have two internal harddrives and I'm burning the project from the spare drive (where all the project media is stored). The idvd4 application is on the harddrive.
Currently I have 17 gig of space available on my harddrive and 40 on the spare drive. I have burned successfully when the drives have been fuller?
I don't want to upgrade at the moment, hopefully I, 'we', can solve the somehow.
Cheers,
Ashley

Toast Buffer Underrun Error from iDVD .img

Happy New Year All.
Need help, iMovie project is 3hrs 59mins, disk image appears (7.46GB) and plays fine.
Toast Titanium 7.0.2 gets to Writing Lead-in/Preparing then returns Buffer Underrun Error. Prevention is checked in Recorder settings.
I've gone done to the slowest write speed with the same result.
Strange things is, whether I drag or navigate to .img to mount the disk image, a "1" in the .img title is changed to a "!" in the Toast window, and DVD Player opens up the image. Is this normal?

Buffer Underrun error message - what is it and how do I fix it ?

I am getting a 'buffer underrun' error message when I am burning to DVD (using iDVD); this means that only soundtrack is fully copied over, but not visuals. Any idea how I fix this ?

Formatting Error.. illegal request...Buffer Underrun

Hi All..
I'm having trouble burning an FCP 5 to DSP 4. I have correctly exported the files to Mpeg-2, using both the File--Export--QuickMoive etc, and/or using Compressor.
I usually get(something like this)
Fomatting Failed. Unable to format disc, illegal request. Buffer Underrun (0x21, 0x20).
I even tried using idvd instead and it happens there also..
Out of 15-20 Tries with new DVD's each time, it only burned twice. Of those the disc would play but none of the menus worked(that could be a me problem, not linking an assest right)
Is this a Super Drive failure, Hardware Failure
I'm going to try the file on campus, and see if I can burn it there on a different MAC.
I'm sorta new to the Mac Universe, so any guidance would be helpful.
Oh yeah, I'm using a Dual Core 2.0 GHZ G5, with a 1GB of Ram, upgraded Graphic card, Latest Tiger...etc

Are you doing anything else on the Mac whilst you are burning - network access, Internet surfing, screen savers, energy savers of any kind - anything that will demand CPU processing power? If so, don't!
This question came up just about a week ago - run a search for buffer underrun in the forum. The situation occurs when the DVD writer is left waiting for data to be sent to it... it's buffer runs out of data. This is usually caused by the main processor being used by some other process and not being able to keep a steady stream of data being sent to the writer.

Recording device reported illegal request: buffer underrun

"Errors found during the burning process....illegal request: Buffer underrun (0x21, 0x02)"
Any suggestions?
Thanks, Kim

Hello Kim,
a buffer underrun occurs when the data stream to the burner is interrupted (i.e. the data is not coming fast enough). As the burner cannot interrupt the burn process, it is being aborted.
This error is commonly associated with burn speed and/or incompatible DVD media. You might want to try to create a disk image and burn that with either Disk Utility or Toast (both apps allow you to control burn speed - iDVD does not).
iDVD 4 disc image burning can be enabled through the patch HPfurz:
http://homepage.mac.com/geerlingguy/macsupport/mac_help/pages/0015-burn_idvdother.html
burn at slow speed (2x) and use high quality DVD-R media (e.g. Verbatim)
hope this helps

BURNING PROBLEM - BUFFER UNDERRUN

Hi!
There is a problem: i have brand new G5 quad and i can't burn dvd's from idvd or dvd studio pro - i have same problem - first computer tells me 'writing led-in data' and after a few attempts i have alert about buffer underrun. (The recording device reported the illegal request: Buffer underrun. (0x21, 0x02.))
What funny is - i can properly burn dvd's from finder! Can anybody tell me what is going on? Don't tell me about no name dvd's - i'm using good brand and i can trust them.
PLEASE HELP - I have bought QUAD for dvd mastering and burning.

Are you creating a disc image and burning that to a disc or are you attempting to burn directly to a disc? Unless you need dual-layer support, I would HIGHLY recommend against burning directly to disc. Both iDVD and DVDSP allow you to create a disc image of your projects.
If you cannot burn your disc image to a disc, then chuck the media (not literally) and find yourself a different brand of media. I also recommend using Toast instead of Finder or Disk Utility to burn your disc image with... you have much more control over the burn speed with Toast.
Also, you have burned DVDs using iDVD or DVDSP before, correct? Just want to make sure that this isn't your first stab at it... you might be building your projects incorrectly.

DVD Burn Buffer Underrun

After six full days of frustration, I made a wonderful discovery about why I was constantly getting the buffer underrun notice, in IDvd, ITunes, Toast, Finder and yes Utility Burn!!!!
It was the Media stupid!!! (Thats for me) I was using Apple blanks, Verbatum blanks and TYK Blanks and every time "Buffer Underrun". I finaly bought some Cheap $15 for 50 Memorex Printable 16X's and Hayoo!! they are burning like champs. Happy New Year to ALLL and to All a good night!!

William,
I appreciate your frustration and am glad that you found a solution, but generally most of us have found Memorex to be inferior to other media. Verbatim still tops my list.
Do a search in these iDVD discussions for media recommendations for more details.
Hope Memorex still works for you, but FWIW, I wouldn't use them again....

Buffer Underrun problems

I recently tried to burn a DVD project in iDVD. However, the first, third and fourth times I tried it, near the end of "Writing Lead-In", it gave me a "Buffer Underrun" error. (The second time I had tried it, it got all the way to "Finishing..." and froze.) I have no clue as to why this could be happening-- I have plenty (over 150 GB) of hard-drive space and 4.5 GB of memory. Burning the same DVD project to a disk image worked fine. Please help!
Dual 2.3 Ghz PowerMac G5 Mac OS X (10.4.7)

Hey there. Are you burning this to an internal DVD burner or one that is externally attached? This can happen not only due t memory problems but also with bandwidth issues with writing to an external drive.
Also, do you have FileVault turned on? If so, this really screws things up when burning DVDs... I have gotten the buffer underrun message with older versions of iDVD when this feature is turned on.

G5 quad buffer underrun error when burning dvd's

4 x 2.5 Ghz G5 Mac OS X (10.4.4)
i just tried to burn a dvd from dvdsp and keep getting a error. it is
Sense Key=ILLEGAL REQUEST
Sense Code = 0x21,0x02
Buffer Underrun
i tried using toast as well with the same result. my dvd drive is also making a lot of noise when it trys to burn. i was able to burn a dvd (data files) using the finder and the dvd burner doesn't make the same noise. i've seen this problem in other discussions and still don't have a sense of what is causing this. some have mentioned bad media, but why would the dvd burner work through the finder and not through dvdsp? or toast?
could this be a software bug or bad hardware?
any help would be appreciated.

There is a work around. In DVD Pro, "format" with the output device set to disc and the format to ".img". When this is finished, open Disk Utility and "convert" the .img file to a CD/DVD master (.cdr). This file can then be used to burn to a blank DVD. If you click the options arrow in the burn dialog before beginning the burn, you can select a speed other than "maximum". Not elegant, but it works. My HL-DT-ST DVD-RW GWA-4165B DVD drive only succeeds at burning at its maximum rate about 1/3 of the time. However, at 12X it has been quite reliable.

PA, ALSA, QL : buffer underruns and crackling audio

i'm running pulseaudio on up-to-date arch, with gnome atm.
The only way i can get the audio in quake live to stop stuttering (spamming buffer underruns in console ) is to set s_alsa_latency in the game very high (a little too high for gaming).
I found a topic with the same symptons on the QL forum but the solutions presented there didnt work for me (s_mixahead and s_mixprestep, s_alsa_latency, s_alsa_pcm to directly acces the divice, bypassing pulse, and setting pulse to time the traditional way). At least not without using very high values for latency(250ish).
I have also followed the arch pulseaudio wiki and the perfect setup guide from the pa website from start to finish multiple times now, but nothing seems to work.
The install is fresh, i reinstalled yesterday. Before that i had the same setup but everything worked (after some tinkering, although i dont remember what i did back then)
So, i was asking myself, could i change something in pulse to fix this, instead of crapping up the latency? Any help on solving this great mistery is apreciated.

Try specifying period_size and buffer_size - see my config below, for more info.
In my experimentation, flash needs a buffer_size of over 6000, roughly.
E.g.:
period_size 1024
buffer_size 8192

DVD writer buffer underrun

My DVD drive in my G5 tower packed in recently, so I bought a Pioneer DVR-115D to replace it. It writes CDs, but won't write a dvd. Every time I try, the system returns a buffer underrun error. I have tried four different media brands, +R and -R, have checked the jumper setting and am about to chuck it out of a window...
Using Toast 8, and the firmware of the drive is 1.12.
Any ideas, anyone?
Thanks in anticipation....

With modern media, 4X is probably going to be the slowest you can burn at. Even at a slow speed of 4X, the drive is burning over 5 MB per second. The DVR-115D has a buffer of 2 MB, so the data stream to your burner from the source location can only be interrupted for less than half a second before the buffer runs out of data and you get the buffer underrun error.
I don't think Toast 9 would provide any assistance in this area. This issue is really a hardware problem.
Where is the data that you're trying to burn stored? Local hard drive, shared folder on a network, etc? What else are you working on while burning the disc? What other programs are running?
You shouldn't be getting a buffer underrun error unless your source is very slow, prone to hiccups, or being used heavily during the burn process.
There is a newer firmware version for that drive, version 1.18. I'm not sure it would help, but it's certainly possible.

Buffer Underrun Protection - Simple Question

Hello. I've searched this forum (and Roxio's) for about an hour, and I can't find a simple answer to this question.
I know that to create a stable DVD for replication, I should have Lossless Linking turned OFF. Yet, if I burn using Toast (which many on this forum recommend), should the "Buffer Underrun Protection" be turned on or off?
The wording in the manual is very ambiguous. Can anyone that knows please spread the wealth?
Thanks
PowerPC G5 Mac OS X (10.4.8)

Buffer underrun protection should be on normally to prevent bad burns, have not heard of it being an issue, maybe someone else here has more info,
Make sure you also speak to the replicator on how they want the DVD prepared.

Buffer Underrun

This is the third time burning a 45min DVD has failed. What does buffer underrun mean??? I export a FCP Movie (QuickTime Movie) from FCP and then let DVD SP do the encoding...I've changed the default settings from Better to Best and from 1 Pass to 2 Pass VBR. What am I missing?
Thanks. Britt

G5 Mac OS X (10.3.9) DVD SP 4.0.3

There are a few ways you can use Toast to burn your DVD.
The following way is the best way to use DVD SP and Toast integrated together.
Author your DVD in DVD SP, be sure to have All Regions checked.
When it is all finished, select Build/Format.
Select your appropriate folder to build your VIDEO_TS and AUDIO_TS folder, then select output device>Harddrive, then DDP 2.0 is set by default.
You will be prompted to save the DVD.img file to your drive. Rename it to your DVD like MY_MOVIE.img or whatever your DVD is called.
When it finishes building/formatting, close DVD SP.
Open up Toast and select COPY
I have Toast 7 so this is how it works.... (Toast 5 did it differently, but still you need to burn a .img file)
Select COPY, then IMAGE FILE to the left.
Drop your .img file into the main window, hit the RECORD button.
This will bring up a prompt for a write speed.
If you are making a master, it is advised to use the lowest speed possible (1X DVD), if you DVDR will let you.
Some only go as low as 4X. I typically use 4X because i use 16X Verbatim media and it only goes to 4X.
A full 4.37gb DVD at 1X is like 55 minutes. 2x is 27min, 4x is 14 min, and so on.
But this is the best way to make a master.
Then you can make copies from this at a higher speed if you want.
Be sure to VERIFY the disc after it burns. It will prompt you to do so.
You can also use the VIDEO tab and select DVD-Video from VIDEO_TS on the left. I would advise against this method although you can. It has to do with the way DVD SP builds your VIDEO_TS folders. Although you set it to all region, if you just BUILD the project it has a RCM Value (Region Code Mask) of 64 (0 is all region). It has a bug which deselects Region 7. Not sure why, but it does.
So if you Build/Format, it will be RCM Value of 0.
That is why it is best to do an .img file and burn in Toast which is better burning software.
Hope this info helps.

IDVD error message "buffer inderrun"

I am trying to burn a quicktime h264 movie in iDVD but keep getting the error message "The recording device reported the illegal request:Buffer underrun. (0x21, 0x02.)"
What does this mean... and what can I do.

Hello corkscrew,
a buffer underrun occurs when the data flow to the burner is interrupted. as the burner can't simply pause the burn process, the result is aborting the burn.
try this way:
1. iDVD is NOT a disc burning app, so leave that work to software designed for it. Instead use iDVD's "Save as Disc Image" option (File > Save as Disk Image). This creates an .img file on your HDD, that can be stored for future use and gives you the option to preview your DVD on your Mac before burning to disc.
2. Use Disc Utility or Toast to burn your DVD at slow speed. 4x is acceptable, 2x (... or even 1x) is better.
3. Use high quality DVD-R (not DVD+R) media (e.g. Verbatim) to minimize burn errors and compatibility issues. Make sure the DVD is compatible with slow burn speed (e.g. 1x-8x)
hope this helps

Cant open iDVD project or even a new project! So mad about to go to Windows

Hello,
I can't open iDVD as a saved project and I can't even go to the window pane that allows me to start a new project because if I open it from the Apps folder, it just opens my last saved project - which doesn't open. Basically it gets stuck and doesn't load the content and beachballs forever.
I just got past an issue with a bad audio file and couldn't burn it to DVD - I deleted all the audio and reloaded the full songs, then burned a disc image to make sure it worked fine (needless to say, when I double-clicked the disc image, it didn't start up in DVD Player like the "great" instructions say). But now, I can't even open iDVD to do anything about it...this is extremely frustrating and Apple support on the phone does nothing, except ask for $199 for a tech to work with you (are you kidding me?!?!!? I paid $2000 for this freaking machine...I'm close to saying a Windows machine is more reliable...but I won't say that)
Anyway, any suggestions? thank you!
Chris

Hi, I got through most of the burning process - however, it "encountered errors" and didn't finish my burn!!! See below for what the info was:
"Errors were found during the burning process:
The recording device reported the illegal request: Buffer underrun. (0x21, 0x02.)
There was a problem during multiplexing/burning."
What does that mean and why can't I burn this project!?!!
Thanks
Chris
