Great advice. Often it is necessary to use more than one technique to get that pesky disk out of the drive. I would add one for those that are using Parallels to run Windows, not withstanding your tag line.
Use the icon in the Parallels system tray to disconnect the CD, then when you return to the OS X side of things you will have regained control of the CD.
