You don't need cd record to make an audio disc.
Simply copy them to a folder (sounds like you already did that) then
just tell finder to burn a disc. Or, you can download softcon audio
burn, and use that program to do the burning as well. Since the cd
recording is built into the os, you don't need a utility like cd
recordto do the recording, and besides, it sounds like cd record is
looking for the wrong device anyhow. I've not used it, so can't say
for sure, but I don't believe the mac cd drives are scsi, they're ata
I think, which would make cd record not work anyhow if it's trying to
use scsi commands.
