Please help. I have been a loyal Dish user for about 4 years. I have been having issues for the past eight months since I upgraded to HD and the 622. I have had 4 boxes and everthing replaced from top to bottom, including all wires, dish and connection components. I have the lat est software installed. I am still having the same issues and I can't imagine other people just live with these problems. These issues mostly happen with full screen HD, but I have seen them other times. They are recorded this way and play back on 2 tvs the same way. I experience my screen getting large green squares all over and sometimes the screen will turn all green. I get video problems that look like the video is in vertical peices. I get picelation for lack of a better word. All these problems happen randomly but mostly with full screen HD video. My signal strength is good. My dish is not blocked and is about 50 feet in the air with no obstrutions even close. It happens in totally clear weather. What on earth could be wrong. I am at my wits end and wonder should I just switch to cable or directtv or is there some way to fix this.
