I have looked through the threads but can't find specific info on my situation. I have a Slimline 5 dish with three HD receivers located 1 upstairs, 1 on main floor & 1 in the basement. The wiring is all run on the outside of the roof and then drilled into the 3 rooms directly. I went to replace 2 of the receivers with 2 HR24 DVR's. Can I simply replace my SL5 dish with a "SLIMLINE HD DISH KA/KU 3 LNBs / NEW SWM / MRV". LNB is a DTV SL3S4R2-01. Power Inserter & 8-way Splitter. Am I correct in understanding that I would need 5 wires from the dish, or is the splitter used inside? I think I read in one of the threads that with the power inverter I only need one line to the DVR rather than 2, but I couldn't find more info. Thanks very much for any help.
