I posted this over at avsforum.com, but haven't got a response yet. Thought someone here might know something. http://www.avsforum.com/avs-vb/attachment.php?s=&attachmentid=32946 TV is a Sony 42we655. I attached a picture to show what is happening. It's worse when paused, like it is in the picture, but it does appear at other times. Using Directv, with a directivo, and a separate box for HDTV. It does it on both. I put in a DVD and didn't notice the problem, but that doesn't mean that it doesn't do it, just that I didn't notice it on that particular DVD. The lines should be smooth, but are jagged as can easily be seen in the picture. I posted somewhere a few months ago about this, and was told it was a bad signal, as I only saw it on that one occasion, but now it's all the time. Signal strenths are strong, so that's not an issue. Could it be the multiswitch, the adapters that connect runs of coax together? The TV? Anything else? Any ideas as to what is causing this? Thanks.
