I just got an HR 24 installed, that replaced an HD Receiver. After a lot of head scratching and web searching ,after the D-TV Tech guy left. I have arrived at a couple conclusions. I already had 2 additional receivers [H24-200 and H25-100 ] With the DVR, I also got the Whole Home option. Just before leaving the Tech hooked up the ethernet from HR24, to my modem,,,, then I had On-Demand, and the roll back to beginning of programs. But, with that ethernet connection, that disables the Whole Home. Why the Tech did not mention that, who knows. Anyway, I ordered a DECA that connects to the system, that is "suppose" to allow On-Demand without disabling Whole Home. From what I understand, there are 3 ways to connect DECA,, Connect DECA to modem [via ethernet cable] then; 1.** Connect DECA to f-coax connector on SWM splitter. 2. Near receiver, place a 1x2 splitter, and connect DECA f-coax connector at that location. 3. Connect DECA f-coax connector to IRD F connector on the Power Supply/inserter. Will any and all of these hooks work ?? ** At the moment, I have a 4 spot SWM splitter,,, have an 8 spot coming,,,, then plan on replacing the fours runs of coax from dish to basement, with one to SWM splitter then branch off to the 3 receivers,,,, this would remove added coax and clean up the install, and lessen outside connection points,,,,,,,,,,,,,,,,,, plus I like to tinker,,,,,
