Just guessing but you may need to read the CD-Writing-HOWTO
very carefully where it applies to ide-scsi modules
such as sg and sr_mod and ide-scsi and their order of loading.

Particularly pre-install options in modules.conf That is
where you put the options outlined in 2.1 of the HOWTO.

If your writer is usb it may not be supported.
