I am still experiencing periodic breakup in both sound and picture while viewing HD. I notice it most on ESPN, probably because that's what I watch most. However, it also happens on all other HD channels. Showtime was unwatcheable one night last week. It is intermittent. When it happens, generally, it is a half second to one second break in audio and some pixilation on a portion of the screen every 30 seconds to every minute or two. It doesn't sound like much but the audio breakups are enough to make me extremely angry while watching something that is dialogue intensive. As I say, it is intermittent, with no pattern that I have been able to observe. Some days it would be fine. Sometimes, it might go days at a time with no problem. Other times it would be bad part of the day, sometimes all day. It is NOT weather related nor is it signal strength related. My lowest signal strength is 91. Most are 95 or higher. Except 103b which ranges from mid 70's to mid 90's. HR20-700, powered from an APC UPS. The latest software was just pushed down yesterday; 0x1b4. I was hoping this would help but it didn't. I have tried turning off and on. I have reset many times, include some RBR's. Once or twice the reset seemed to help, but it seems to not help lately. Being an intermitent problem makes it pretty tough to pin it down. I have disconnected the ground from the grounding block, and have reconnected it... no change apparent. I know this has been brought up before but have never seen a solution. Anybody? Anything?
