DVD stuck/jammed in tray

My child put in a DVD incorrectly and it's now jammed inside my Tivo. Can't find a pinhole or any other type of release for the DVD tray. How can I manually open the tray and remove the DVD? I've already removed the cover, and tried to remove the DVD recorder, but can't remove it from the front of the machine because the front part of the tray (external facade) is wider than the DVD unit inside the Tivo.
