Use disktool and System Profiler to eject stubborn CDROM discs. The short instructions (excerpted from the article) are:

Run the System Profiler (Apple menu -> About This Mac -> More Info).
Clicked on the “ATA” section under “Hardware” (left pane of System Profiler), then look for a Matshita device in the ATA Device Tree (right top pane of System Profiler). Clicking on the Matshita device in the top right pane shows detailed information in the bottom right pane: Need to know the “BSD Name” of the drive. It may be: “disk2″.
Open a Terminal window and enter the following command:

disktool -e disk2

This will eject the optical disc.
