I am in Tulsa and are HD locals came up a few weeks ago on SAT 99. Saturday night during the Nascar race it went to "searching for Sat" just on my HD locals, other HD channels where fine. The locals did come back up after maybe 30 mins. and as far as I know stayed on. Yesterday during the Hockey game on NBC it did the same thing, and then they came back up after 30 mins. or so. When I check the signal strength I am pegged at 94 steady on two transponders on the 99 sat, 4 and 6 I think. So, I called the local comapny that put the dish up and they came right out this morning. Of course the channels where working fine. But, he called tech support at D* and they asked how the HR-700 was plugged in. I have it plugged in a Battery back up block down on the floor. And right off the bat they said that was the problem. They said the the MPEG 4 signal can be screwed up easily by electrical interference??? and to plug it straight into the wall. So we the Tech and I thought the was a bit strange but plugged it straight into the wall. Is that possible that a UPS device can screw up a MPEG4 signal?? I feel like there is something else wrong somewhere.
