As a starting point.

Check permissions on /dev/cdrom and which ever device /dev/cdrom
points to if it is a linked. Check /etc/fstab (or whatever the
automounter equivalent is in Ubuntu) to make sure that the cdrom is
mounted without any unnecessary options. Also check the permissions on
the mount point.
