There is nothing like "speudo SCSI" CD/DVD writers only work with SCSI commands.

As you might know that more than 6 months ago, cdrecord has been enhanced to
autoselect the target in case that there is inly one possible drve in the 
system. Verify by:

cdrecord -inq

If this gives you the inquiry data for your drive you may omit the dev=

The preferred program still is cdrecord.

Cdrecord has been tested to correctly support double layer DVD+R media.

If you prefer to write in a less compatible way, go for other programs than
