I recently got a Duo 222 receiver, and it's hooked up to my HDTV in one room, and my standard TV in another room. The other day, while watching the SD TV, I noticed the picture seemed "bigger" than my TV. What I mean is, it's like a certain amount of the picture has been cut off at the edges. I tried going into the menu to see if there was maybe a way to put it into letterbox style, so I could see the full picture, but I couldn't find any settings like that. Strange thing is, when the guy came out to install it, I saw that the picture WAS letterboxed when he was making sure it worked, and he played around with the settings on it to make it go full screen. I didn't think to ask him how he did it, as I figured I'd be able to figure it out, but I'm stumped.
