I've not seen this problem you are describing, so will have to take it 
on faith.

obviously from the mount command, Nautilus did see and and mount the 
disc exactly as it should.  Presumably, your problem therefore is that 
you have no icon in under the "Computer" location, but that's easy to 
work around.  You can browes to the /media folder to access the files, 
and you can can use "eject /dev/sr0" to eject the disc.  (Make a custom 
launcher with this command, and put it somewhere convenient for you.)
