So, my wife and I were watching the election coverage last night. I went upstairs to tuck my kids in and when I came back down, all satellite channels were getting 771 - searching for signal on my main HR20-700. Only the OTA channels would come in. I checked the HR21-100 in the living room and it was fine. I tried redoing the dish setup and everything was set correctly - still couldn't find the satellite. Finally I had to pull the plug on the HR20 and plug it back in. Once it came back up everything was fine. Something must have happened - we didn't lose power or anything. Any ideas?
