If you still have that problem on current 10.04 or 10.10, can you please add my sru-test PPA at
then upgrade your system (which will upgrade udev), and report back how it goes? If it still does not work, please describe the kind of medium which you inserted, open a terminal, and do
sudo /lib/udev/cdrom_id --debug /dev/sr0
(with the medium inserted) and copy&paste the output. Thanks!
