I am receiving DirecTV on 101 (SD) in the Caribbean with a 1.80m Dish, and dual LNB. Currently, I have a setup with a DVR, and 2 additional receivers, making good use of my 2x4 switch. Is there anyway I can add another receiver ? I've bought a 5x8 Switch (Aspen S4180GX), but I'm not sure of the right way (if right way there is) to hook it up. Suggestions welcome...
