I am confused. While watching the latter parts of MNF, I checked my onscreen format (I have a Mitsubishi DLP-51'). It clearly stated 1080i.
I received that game in Standard 1080i- Full Screen HD. I was offered an option of 1080i-Wide Expand. Of course I chose the standard 1080i, and it was beautiful. I have my STB (8000HD) set to output, 1080i, 720i, 720p. 480i and 480p. And while I have my STB set to all those options, I have yet to see an indication that 480i,480p, 720i or 720p is being outputted by the box.
Is it possible that my STB was outputing 720p, while my TV was upconverting it to 1080i? I can't think of any other explanation. But in any event the picture was gorgeous.
One other question: In watching NBC (channel 3- analog). The side bars appear gray. When I change to NBC HD (channel 733) the sidebars appear black. YET. although the WIDTH of the sidebars, the image betwen those sidebars is slightly wider on Channel 3 than on Channel 733.
