I'm in NC and having the exact same issue with our 3800. Most HD channels pixelate and get choppy sound almost everyday. Today for some reason 1 channel I tried was alright, but most of the time its just awful. I called them today and all I got was the 3800 CAN have that issue cause it's kinda old ... and that I could always go trade it in for a newer box. Plus we have internet through them and it just completely dies at least once a day and they dont even know why. Nothing has changed with our wiring or TV or anything of that setup so my hubby and I are at a total loss. Its getting old FAST though.
