If the DVD burner is seen by Dom0 as a SCSI device then scsi passthrough should
allow it to work.

GPLPV supports the scsi passthrough so if you are using that you might have some
success but I''ve never actually tried it. If you try it and it
doesn''t work for burning, send me the details and I''ll see if
I can fix it.

You do need scsi passthrough backend support in Dom0 though... what Dom0 kernel
are you using?
