I have similar issues with buring to IDE drives under Windows that go
away when I enable DMA for the CD burner.

There are a couple ways to do it under Linux (note that most of these 
are untested - the only way I've bothered trying to burn under Linux is 
with a SCSI burner):
  * hdparm -d1 /dev/hd<whatever>
  * If you're compiling your own kernels, there's an option called
    "Enable DMA only for disks" under "IDE, ATA and ATAPI Block devices"
    that should be set to "No"
  * On your kernel command line (ie the paramters you pass the kernel on
    boot): ide0=dma if it's on the primary channel, ide1=dma if it's on
    the secondary channel.
