Here's a thought....

Perhaps enabling DMA for your burner would help.

Add this to the end of your /etc/hdparm.conf

/dev/cdrom {
        dma = on

"cdrom" could be changed to any symlink that points to your burner. Or it 
could point to something like /dev/hdc, or what have you. 

To test this before making a change, you could try:

sudo hdparm -c /dev/hdX 

....where 'X' is the letter for your burner.

Don't know if this would help with the burning, though.
