Some time back Alester Crooks posted a little cdplayer program to 
play audio disks in SCSI attached cdrom players.  I found it to work great
with a little NEC cdrom player I have, as well as a Matshita player I
picked up at a flea  market.  Since I could do this successfully under
0.9A, as well as 1.0 a year ago, I guess I'm confused by this debate.  Can
anyone shed some light?
