Try checking to see if any program has a file open in the cd.
If you open a terminal and change the current dir to one on the cd, it will lock it as well as a open file.
I had fun and games with that ones.

If all else fails you could turn the lock off with: echo 0 > /proc/sys/dev/cdrom/lock 
I'm sure you know that you can add the setting to /etc/sysctl.conf
