Just wanted to chime in with something I found out last night.
I have been using the component cables that came with the 811 for about a month(Got dish the day after christmas) and the picture qaulity for both HD and SD was not near as good as a previous HD reciever that I had(with a different company). I figured it was just the 811, but last night, I hooked the 811 up to my TV with the crappy/cheap component cables that came with my other HD reciever, and the picture qaulity for both HD and SD drastically improved, so much so, that it is even better then it is with the old HD reciever(I had them both hooked up, and was comparing PQ).
So, I don't know if most of the people that are complaining about the PQ on the 811 are using the cables that came with it, or what... I was, just because I assumed that because the cables were so thick, they would be better then the cheap ones that I already had. BOY WAS I WRONG.
