New to forum, lots of really good info. Heres my problem. I had the 211 with HD pack installed last Saturday now I'm seeing ripples on the TV screen. It ranges from a perfect picture to ripples so bad it's unwatchable. I have unhooked everything from the receiver except the component cables and it's still there. If I change the input source on the TV I have a perfect picture. I've tried using a different set of component cables, no change. The only thing that works is changing the HD setting on the receiver to 480I or P. My TV will not display 720 and it automatically detect the input (480 or 1080). Any ideas? I have not tried CS yet, figured I had a better shot here. On a side note the same day as the install I had pixelization and video freeze on the HD channels at least a half dozen times in a couple of hours and one case of "black screen" audio, banner info and guide but no picture, had to re-set, has not happened since.
