Tivo Parental Lock Hack

Under certain circumstance it is possible to bypass the parental lock feature. If while viewing a recorded program that is normally locked. If you press Guide to exit back to live programming and then down arrow to the lock and relock the receiver it shows everything is locked back up. This however is not true. If you just left arrow (back button of sorts) it would normally take you back to the previous screen. In this case it takes you back to the locked program and begins the play of that program.
