I did some background reading and hope I'm getting this correct. I have DirecTV with four leads coming out -- two go to the Tivo in the living room and one each to separate tuners in the basement and bedroom. Currently that's fine for my needs. However, we're doing basement work and intend to have another Tivo in the basement plus we're drywalling the basement ceiling, so I have to make sure all electrical/connectivity stuff is taken care of "forever more". So on both accounts I want to expand the number of connections to my dish beyond the 4 I currently have. Is it as simple as getting a 4x8 multiswitch, plugging all four inputs into it, and then running the 8 outputs in whatever way suits my needs? If that is the case, what is the point of connecting all 4 into a single multiswitch, can I, for example, connect each correct pair to a 2xN switch as necessary? Thanks.
