Have you tried to re-assign the eject function to a new different key, and then back to the original key again?
That would be my first approach.
On another thought what regional keyboard layout do you have assigned to your keys? Maybe there's a mix-up and ML is just confused by it...(I know, I know, but with computers all's unreasonably possible).
I don't know anywhere in the System Preferences where you can program a different button for the eject key. The keyboard is a US one, but all of them have the eject button in the same place as far as I know, to the right of F12.
It appears to be that Mountain Lion thinks that our DVD drives are not internal anymore. Try launching DVD Player and it will tell you that a valid DVD player could not be found.
I fixed that problem by editing /System/Library/Frameworks/DVDPlayback.framework/Versions/A/DVDPlayback with 0xED app and replacing any reference to "Internal" with "External"
This makes the DVD Player work but as far as the OS is concerned the drive is still external and F12 will not work to eject.
This is probably a clue, I am getting the same message. Thanks for the workaround.
