Do really need the ide-scsi?
If the kernel version is 2.6 it isn't needed for IDE writers.

I'd suggest updating growisofs. Different drives have different
tolerances for the media they will write. If the newer drive is
a lot faster than the old one, it could be a throughput issue.
You might also try different media. The list had a thread a while
back about good manufacturers.
