DTV came out and upgraded my dish and receivers for the service. There is one cable from the dish to the SWM (think that is the name, one connector on one side and 4 connectors on the opposite). I have an HR24-500 as my main receiver. There is a black box that says "SWM ODU" Only for my main receiver. In our Living room I have an H24. This particular setup works fine. The Living Room receiver can see the Main Receiver fine and everything works like it should. I added an H23-600 in our bedroom and ran the cable to the SWM block outside. Signal is fine but I can not get it to find the DVR on the main tv. When I go to setup it has "authorized" for WHDVR and says "no networked DVR found". I have reset all the receivers multiple times. I am pretty sure it is user error as everything works fine except what I installed. :lol: Do I have it all hooked up right or am I missing something?
