Here what I have in my home: I have one HR-200 and standard receiver in my living room I have one DVR SD 2 tuner receiver in my bedroom I have one standard receiver in my daughters room I want to add another HD DVR to replace the standard reciever in my living room, but I need to run another line so I can have 2 tuners. Is this hard to do? Where to I connect the line? Is the muliti switch outside or in the attic? I dont have a clue what to do. Running line is not the problem for me, it is where to connect it. Any help would be great!
