Ok, just got a Pioneer 43" Plasma HDTV, also added a new HD Tivo (250) receiver. I had a problem w/ my old TV - it would sometimes slow down & pixelate real bad. Also, just seemed really slow w. alot of pixelation. After the new TV & receiver it it still doing it. I have read of this issue & it usually being a hard drive, now I am guessing that is not the problem as I have a new receiver. Any ideas? Yes, I have re-booted, I've pulled the cables & tapped the ends (this was recommended by DirecTV customer service) seemed a little hokey to me. Should I replace the sat in cables & just keep going backwards toward the dish? Thanks for the help.
