Which is a problem for my Myth box, which is in a conumer electronics style
case with only room for one DVD/CD drive.

I'm writing to /dev/dvd, which links to /dev/hda so that's presumably writing
to the drive directly as an IDE device. I'm not sure how I'd use SCSI
emulation on the device - any suggestions?

It's the only PATA device on the system - the hard disk is SATA.
