I have a Mit 55", I am using a Tivo Series 3. When I set the Tivo to 1080i fixed my HdFury 2 works amazing, but it will not work with my Xbox nor my DVD player. Any ideas? I got a new Amp (Denon 2310) with the intention of running everything through it and then to the TV. The Tivo worked, none of the others did. I tried to run both to the TV using the HdFury2 but they didn't show a picture. Help!
