I had a Dish 500 installed so that I could get the Milwaukee HD locals. Since the installation I have had problems with the picture. It will pixelate and break up. sometimes so bad that you can't watch them. It doesn't matter which channel I am watching (NBC, ABC or Fox). I called tech. support and they sent a guy out to check it out. He couldn't find anything wrong, but replaced a wall plate that he thought might be bad. I still am having the same problem. Is any one else in the Milwaukee viewing area having trouble with their HD locals?
