I bought an HR20 off Ebay. I have it hooked up to replace one of my old receivers, which was a standard receiver. It goes through the initial boot up stuff. It gets to step 2 of the setup and goes through the progress bar until 100%. At this point it goes to a searching for satellites 771 screen. I have it hooked up to Sat input 1 on the receiver. I've tried Sat input 2, but that one doesn't make the progress bar ever appear. I called direcTV and they said that they need to send a tech out. I don't think that is the case. Any help, as I'm stuck at this point. Please post suggestions, but I won't be able to respond until around midnight or tomorrow morning. Thanks for your help!!
