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?
