For anyone with a RGN200 Comcast Cable Box you can set the picture format by shutting off your TV but keeping the cable box on. Push the Menu and Info button at the same time and that will take you to the HDTV Wizard. Follow instructions there and you can set the picture format

You have to keep the cable box OFF and THEN press the Menu and Info button [on the DVR box].........you will hear a click.........the DVR will NOT turn on........but the TV format wizard will be seen on the TV.
