Mitsubishi Model WS65905 HDTV We are connected and viewing from our Blu Ray DVD player but not at 1080i. The output is 480i. How do I change to 1080i on the TV? There is no "advance" icon available on my settings menu and I have run through all others. Have no problem changing the settings on the DVD player. But when I do, there is no picture on the TV. Thanks, Steff T.
