The problem I am having is that when I switch between my Local HD channels and some of the other HD Channels (ESPN, Sunday Ticket HD) I keep getting the Searching for Signal on Satellite in 2 (771). Usually the channel eventually comes on, but it takes anywhere from a few seconds to a few minutes. Rebooting the box usually corrects the problem for a little bit, but it eventually happens again. This is a new install, I had done on the 8/29. I have one black DVR box hooked up to the dish. Is there anything else I can try to correct this, before having to contact Directv. Also all the signal strengths appear to be in the high 80's to low 90's.
