Hi I currently have an HR24 in my living room with the power inserter and cinema connection kit, an H21 in my family room with a DECA attached to it for MRV, and an R16 in my bedroom. I was able to get DTV to replace my R16 with an HD receiver (non DVR). I am planning on moving the HR24 to my bedroom and putting the new HD box in my living room. Is it as simple as unhooking the coax from the HR24 and hooking it up to the coax in my bedroom, where the R16 was. I would then just hook the new HD box (and deca if needed) to the coax in the living room that the HR24 previously was at? I would leave the power inserter and cinema connection as they are now, no need to fuss with them?
