    Is there a way to determine how compressed a particular channel is? The reason I ask is I had my HR20 record the Wimbledon Mens finals starting at 6am PDT (in HD on NBC). I originally started watching it on my Samsung plasma TV and noticed a judder in the picture from time to time. This was a concern to me as the samsung TV I have has had reported issues with judder when horizontal tickers are present (another story not appropriate for this forum). After freaking out I decided to switch to my front projector as the display and noticed that it too had the judder I was seeing on the samsung plasma. I'm assuming that since I can see the judder on two different displays that the cause of the problem is the HR20 and am wondering if it was caused by the signal being compressed more than normal. Anyone have any opinions on my theory?

    Some SD channels look VERY good.. but others.. like LINK look so horrid! I would really like to hear this answer too. They should REALLY just make all the SD channels the same... lower the really good quality channels and raise the poorest channels. Be fair!

    Actually, the source for Wimbeldon feeds was not HD; NBC did the best they could with an upconvert, which may have een the source of your problems.

    You are assuming that the PQ is solely the responsiblity of DirecTV. Some stations are just horrible to begin with and cannot be made better.
