Cool command:
lsof -n | grep /dev/cdrom
This will show if any process has an open file handle on /dev/cdrom. There have been problems with gam_server IIRC fondling your cdrom. If that is who is touching it (and so stopping the unmount) have a google / look through bugzilla about gam_server.
Another way to get the problem is if you have a terminal open with your cdrom mountpoint as the current working directory. That'll show up from lsof -n too.
