Player seems to have eaten the DVD. Will not release it so can be ejected

If the eject button does not work, try opening "my computer" and right-clicking on the icon and choosing "eject."
If this doesn't work, get a large paper clip and straighten it out and put one end in the little hole in the below the CD drawer. That will open it a little and you can grab it and pull it the rest of the way.

If it's a desktop, you can manually eject the disk. Turn off your computer and press a paper clip or other small object into the little hole on the front of the DVD drive. You need to apply a little force, but the tray should slide out far enough for you to remove the disk.
