DVD's, located on the main Vizions Media custom GUI, will only be viewable when a DVD is inserted in the DVD slot. When a DVD is inserted into the slot, the DVD will automatically start and when finished playing or stopped the DVD screen will appear. This DVD screen is a notification that a DVD is still in the tray. If you had inserted it and then hit stop, waiting for guests or family to arrive, then you would go to this screen and depress the select or start button on the remote. Once the DVD is started you have full control of all the options including screen aspect ratio just as if you had preformed a backup.
