Hello.

More or less, I've lost my sata dvd drive ;)

(cd0: <HL-DT-ST DVDRAM GSA-U20N HX11>)

Although I can mount CDs, cdparanoia is not working, 

003: CDROM reporting illegal number of tracks

cdda2wav as well..

cdda2wav: Error 0. inquiry: scsi sendcmd: fatal error
CDB:  12 E0 00 00 24 00
cmd finished after 0.000s timeout 60s
Inquiry command failed. Aborting...

cdcontrol play produces no sound..
(but it probably wasn't working with atacontrol either)

mplayer stubbornly wants to play dvd:// as /dev/acd0 ,
using "mplayer /dev/cd0" plays first track of dvd, 
trying to play cd with this command leads to:

Playing /dev/cd0.
Seek failed

I think that If mplayer would interpret dvd://(track) as
/dev/cd0(track) original functionality should be restored.

For now NCQ has stripped me of ability to watch DVDs
and rip audiocds ;) Well, trade-off. 

-best regards,
