Ok, this is my first post so be patient with me. Let me explain my setup, and then I'll ask the question. I have a Dish system...two dishes (3 lines) into a switch in my attic. Out of the switch is 4 lines to 3 receivers...one of the receivers is a duel (2 room) receiver. Here is my question...in my living room, I have one single satellite input that went to my PVR receiver. Recently I aquired an HD receiver...my problem is, I want to hook both receivers up to my television, preferably without having to run a second line into my living room. I've tried a diplexor but that didn't work. How would I make this work...and please don't tell me I could have waited for an all in one HD/PVR receiver, thats irrelevant now. Could I add a second switch in my living room before the two receivers? Would I have to add a second switch in the attic and run another line to my living room? Any help would be appreciated. Thanks!
