I have two HR21-700's. The first runs my living room which is on the far side of the house away from the dish. The second in the bedroom needs only about forty foot of wire to run from dish to receiver. Receiver one in living room works great. Receiver two in bedroom if recording show say on 229 will not get signal on golf channel or few other HD channels such as Espn. I can stop recording wait a few minutes and golf channel will begin working. It almost seems like while recording it is sucking all signal strength....which I don't think is possible. Was hoping without searching and reading for hours that someone would know or seen this problem in the past.
