               ^^^^
Sony haven't got one right yet that I know of..
They seem to think that SCSI2 refers only to data commands.
If tehy implimented SCSI2 audio on that drive it's be their first..
(you might talk to them...)
also
I think the "workman" player, knows abut the SONY commands
and I THINK (but don't know) that it uses the direct user-SCSI
facility to shove them down the throat of the device..

(one of the other players does and I think that's the one)
