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.

4 x 2.5 Ghz G5 Mac OS X (10.4.4) dvdsp 4.0.2

Maybe you´ll be successful with lower burning speed. DVDSP automatically uses the fastest possible speed which you should avoid because the error rate will be higher.

Try to burn your DVDs at the lowest possible speed with toast (oh, and try different DVD brands!).

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.
