I'm a new member to the Dish Network family and I received a VIP722 box. I have a fairly old HD TV. It is the Sony Trinitron KV-32HS500. When I view a channel in HD, there are no problems, the TV is square but the picture presents in widescreen. However, if I view a SD channel, the channel displays as a square WITHIN the widescreen area. Meaning, the square is smaller than the screen itself, with probably 3 inches of no image all the way around. I am not sure if this can be corrected from the sat box or the tv itself, but I have tried messing around with options on both and cannot solve the problem. My TV is set to 16:9 auto, which means it should automatically fill the entire screen if the image changes. Pressing format on the remote on an SD channel zooms the SD channel to widescreen, stretching it, but not filling the entire screen. Is there anything I can do?
