Hello, I just got hooked up yesterday. I had them hookup an 811 and a 522 on my HDTV. Today the 811 doesn't see the sat. at 110. The 522 does, and if I switch one of the cables from the 522 to the 811, the 811 still doesn't find the sat. The check switch said that it is hooked to only one sat. This looks like I have a bad receiver. Thought I come here and ask the experts. One more question, has anyone hooked the output from a 522 into one of the inputs of an 811. So they can watch the program from the 522 through the 811. So you don't have to change TV inputs, and it would show up in the guide. TIA, James
