I have a triple LNB directv dish that goes to two receivers. One upstairs and one downstairs. I recently won (haven't received yet) a z552 Digital Entertainment Center. It's basically a media edition PC-DVR with dual tuners so it does not have a satellite receiver built in. I would like to hook up my dish so that I can use both tuners on the DV. The wiring for both receivers are in the walls so even if I did move the receiver that is downstairs to upstairs, the wiring would be problematic. What is the best way for me to hook up both receivers to the dual tuners of the DVR
