Step #3 in comment 5 above works for me:
3. 'sudo eject -i off'
So it seems that the drives are locking after eject for some reason?
For me, this happens on Lubuntu 12.10. I can insert one CD and eject
it, but then the drive is unusable again until I issue the command
above.
It only happens with my DVD reader (/dev/sr0), not my DVD writer
(/dev/sr1). lshw taken after issuing the command above, both drives are
in fact empty.
