A couple questions from a newby with little clue with when it comes to the whole HDTV revolution. At this time I have a PVR 501 connected to my 60" Grand Wega with a S-Video connection. SDTV signals are not very good, especially with wide zoom, etc. I have ordered a 811 receiver that will be here Saturday. I was wondering, first and foremost, can you receive HDTV signals from local channels through the subscribed Dish signals that I currently receive on my 501 PVR, or must I have an OTA antenna. (May be a dumb question). Second, how can you receive widescreen format signals to match the format of my Grand Wega? Any help and input from Sony Grand Wega owners out there would be greatly appreciated.
