since I upgraded to the HR20 DVR I noticed a slight shift in my screen. I have a 65 inch big screen rear projection. Ialso have a reciever?tuner. I never noticed it on my HR10. For instance when I was watching the NFL network thursday night games IN HD I noticed that the top was chopped off I could see half of the info.(score, time what down etc). The bottom of the screen has the picture isnormal. Last night I was watching Grey's Anatomy and during a comercial that was not in HD ( bars on the left and right) and was in letterbox black on top and bottom I noticed the balck bar on top was thineer than the one on the bottom. I have also noticed that at times when the info banner is displayed the channel like 40 I can't see the 40 only half of it. Though if I shut off the units and turn them back on it goes away. BTW I have the HR set as stretch. This problem in HD andNON HD. I hope this makes sense to some of you out their. I figure better to ask you guys than D*.
