OK so after a long thinking period I decided to re-up with D and they gave me a 2nd hddvr for free and I am trying to get it all hooked up but had a couple questions. The hddvr that I have in the living room has the single wire setup and they did not include that part with the hddvr for the bedroom. My question is do I need to instal the B band converter modules in the bedroom or not. The instructions that come with the BBC states that "a BBC Module must never be used in a system that contains a Single-Wire Multiswitch, the equivalent BBC functionality is already contained in the SWM". Does that cover BOTH tv's or just the living room tv?
