I have HD direct at my home. I took a non-HD receiver to my lake house, put up a dish. Everything was fine, I got my local channels from my home at the lake house along with all the other channels, not HD. This was last fall. When I went back this spring I had local channels for a very short time, now they are gone. The guy who put up my satellite dish put up a new one that would receive 3 satellites, the other would only receive 1. We took the receiver back home and it worked fine and it received local channels. We took it back to the lake house, still no local channels. My installer at the lake house is saying the reciever needs to be remapped by direct tv to work with the new satellite dish at the lake house. He said the receiver is mapped to the different, larger dish at me home??
