Apparently the presence of the SB Live! audio device might even
accelerate the problem, although it does not actually disappear when
this PCI card is removed. When i moved to Linux, i decided that
writing a kernel patch based on the fixup programs i found for windows
98 would be appropriate.
Just FYI, the onboard "SBLive" is not a real SBLive! - it uses a newer,
cheaper, and vastly inferior chipset that moves all of the interesting
hardware features of the good old SBLive! into the (Windows) driver.
I would be surprised if it had the same issues as the original emu10k1
chipset, which generated a lot more bus traffic by implementing multiple
stream mixing in hardware.
IOW, this bug is probably unrelated to the SBLive...

Lee,
I might have led you to think i meant an onboard card because of my
wording, sorry.
It's a PCI extension card, here's some output from lspci:
00:09.0 Multimedia audio controller [0401]: Creative Labs SB Live!
EMU10k1 [1102:0002] (rev 08)
Subsystem: Creative Labs CT4832 SBLive! Value [1102:8027]

However, you're right, the role of this sound card in creating or
accellerating the data corruption has been
disputed. I might as well be irrelevant. When i remove it, i still have
data corruption problems when burning
DVD's. I've tested all this back when i was investigating to make sure.
The discussion, (iirc, because i can't
find the specific articles anymore) revolved around Creative
interpreting certain PCI specs wrather loosely.
