I am running an Xbox through component cables to the Component DVD input on the 1070. Then I use a component cable from the Component Out on the 1070 to the TV.

With the TV set to the component input I am able to view Xbox games which are being output in 480p or 720p. But I am not able (new problem) to view movies being output in 480i. I do get sound with both games and movies.

I did not have this problem until yesterday when I hooked up the following:

Samsung ATSC OTA tuner with DVI output to the DVI2 input on the 1070 and back out to the TV through the 1070's DVI out.

So why am I having problems now?

I read a similar question in another post but I am having trouble wrapping my head around it. I am getting 480p and 720p output through the component but not 480i. Is it a coincidence that the problem started with the introduction of the ATSC tuner with DVI?

Argh, no cable and nothing on TV I want to watch a movie. Please help!
