	ide-scsi should not be necessary.

	I have personally seen xine play Hellboy...

	This stuff strikes me as bad. Also, it does not show the whole picture. 
The stuff inserted into the dmesg ring buffer at bootup has long since 
been pushed out. What does the same command report after a fresh boot?

	Did you say that this optical drive used to work and that the DVDs used 
to play? Did anything change on your system?

	Other experiments: Insert a random CD-ROM (not audio CD). Can you mount 
and read the ISO-9660 filesystem using this command:

   mount -t iso9660 /dev/hdc /mnt/<mountpoint>
