I had two HR24's setup as part of the Whole Home DVR package. Each other could see and playback the others programming. I added a third one HR24, and that HR24 - when set to the EXACT same settings as the first two - it does not see any content of the others and the other two do not see it. DirecTV was unable to provide any answers - they did not set it up - it was purchased from the company who setup the first two HR24's. It's setup as SWM (one cable to each DVR) and there is a little booster off of one. No Ethernet involved. Is there anything that I can try that the DTV CSR person did not know?
