vip622 pixellation question
I just got my dish network HD hookup. It is a vip622. I bought a Vizio 37 inch tv. HD channels look great, but, I am noticing a fair amount of what I think is referred to as pixellation. I mostly watch the nbc/abc/cbs HD channels and the picture sometime freezes with part of the screen fine and the other part is like solid green. Then, a few seconds later, the picture seems to refresh and all is fine. My best description when it freezes is like a puzzle on my screen with a quarter of the pieces missing, then, it corrects. I do notice this with fast motion changes. Is this a receiver issue or hd broadcast issue? Anyone else having this problem. I am using 720p with Phillips hdmi cable.
