Yeah, /dev/{cdrom,cdrw,dvd,dvdrw} all exist, and point to /dev/sr0:

jmoe@aus8617 ~ $ ls -l /dev/{cdrom,cdrw,dvd,dvdrw}
lrwxrwxrwx 1 root root 3 Jan 14  2011 /dev/cdrom -> sr0
lrwxrwxrwx 1 root root 3 Jan 14  2011 /dev/cdrw -> sr0
lrwxrwxrwx 1 root root 3 Jan 14  2011 /dev/dvd -> sr0
lrwxrwxrwx 1 root root 3 Jan 14  2011 /dev/dvdrw -> sr0
jmoe@aus8617 ~ $

And if I try to mount a data CD or DVD, or watch a DVD, I have no
problems.  It's only audio CDs that give me issues.
