Anyone else have this problem? We occasionally get this curious phenomenon mostly on ABC 7 where the screen breaks up into six smaller panels. It is related to pixel loss which occurs more frequently with all the network locals in HD, and of course it goes away as soon as an ad appears. We keep thinking it has something to do with how we use the 722 system - recording two HD programs while watch another and skipping through commercials. But the timing of the problem implies that it may be the feed.
