What makes you believe that this is so? I've seen this discussion a lot on
various newsgroups and the result was most of the time that the overhead was
neglectable. AFAIR, the ATAPI command set that is used for CD-ROMs / CD-Writers
is so close to the SCSI command set that the "emulation-overhead" is hardly
noticable. I'm using an ATAPI-DVD-drive with SCSI-Emulation and don't have any
noticable decrease in performance compared to native ATAPI-mode. It's important
though that even in SCSI-emulation-mode the DVD-/combo-drive has to be in
DMA-mode. Otherwise you will have skipping DVD-playback.
