Yes. By the way, does it work now?

I set up all DVD/CD drives with scsi emulation, mostly because at least
until some time ago, some graphical programs for cd writing only
displayed drives with scsi emulation, even for reading. Another plus is
that you can easily access drives with emulation if you are in the
cdrom group (for example for making images). If you don't use ide-scsi
emulation, the device files belong to the disk group (like ide hard
disks), so you have to change ownership, or add yourself to the disk
group, which is a very bad idea.
