This is a huge thread and I skimmed it a bit but can't seem to find an answer to this.
I understand that any HDTV is supposed to take an incoming signal and scale it to it's native resolution. Why then, when I press info on the TV remote does it show it displaying as 720x480i? Because when I watch an upconverted DVD, it shows it displaying at 1280x720p. Also, I was at a friend's house last night, and they appeared to have a new Motorola box. The only way I could tell it's different is because there are no front A/V inputs and the red light was in the top right corner instead of the top left corner. This box appeared to be changing all 4:3 signals to 16:9. We weren't watching any of the shows in HD, I can be sure of that. So how do I get the aspect ratio to change from 4:3 to 16:9?
