The Panasonic DMR-EX78 DVD Recorder has several disc settings to control disc playback, including a ratings level lock feature to protect children and others from certain viewing material that you have deemed inappropriate. The feature allows you to lock playback of discs that have a certain rating by setting the recorder to that ratings level. Once the feature is set, unlocking it requires that you access the DMR-EX78 "Disc" menu using the recorder's remote control.
