That's an easy one: You can still enable DMA, even when using ide-scsi:
either you're lucky and your particular IDE driver has an option that
enables DMA (either a kernel option or a parameter to insmod/modprobe)
or you'll have to enable DMA manually:

just use "hdparm -d1" on the _IDE device_ for your DVD drive.
eg. if your DVD drive is the master device on your secondary interface,
you use "hdparm -d1 /dev/hdc" (just disregard for a moment that you're
usually referring to the drive as /dev/scd0).

Cheers,
