Upside down dvd inserted

FYI - This might damage the unit, but if you really need to get that DVD out then you can try this at your own risk!

Try unpluging the unit, then plug it back in and press the power button and a split second later press the eject button. This all needs to be done quickly otherwise the unit will try to load the disc.

Or

You can try letting the unit load the DVD. When the unit says "Please eject disc. Playback feature may not be avalible on this disc," press the eject button.
