Right, there was a solution posted some time ago, where you deleted some 
access rule to the device and when you rebooted it was newly created 
fresh. Instead of /dev/cdrom0 you got /dev/cdrom. Same with /dev/dvd. 
But, it seems there are new things in 12.04 afoot, so I have no clue if 
an old fix with still do the job. Again, when I did a FRESH install, I 
had zip for problems.

Is udev still in use?? Ric
