Reception has improved recently - DirecTV DVR

For Reception has improved recently, relating to DirecTV DVRs and receivers. We were having similar problems as other people since around the time of the SuperBowl (pixelating, ghosts, freezing, high-pitched squeaks) and even called DTV several times about it, although they claimed the nearest problems were in NC. We now notice that it hasn't been doing it for the past week or so. We're located in SC. Perhaps they fixed something up there afterall. :)
