Hi guys, got a problem that I haven't found an answer to yet. I have a Phillips DSR 704 DVR that has been working great. Recently it has started pixelating the image and the audio gets garbled for a few seconds. At first I thought it was a cloud moving across the sky or something, but it has started doing it more and more frequently. My signal strength has not changed so I don't believe the dish has moved since it was installed (although I haven't gotten on the roof to check). I have 2 other receivers in the house (RCA Model DRD435RH) and I do not have this problem with them. Any ideas? Thanks for any input.
