hi all - in my current setup, i have three coax cables coming off my dish. two to my directv/tivo combo unit (in the living room) ... and one to my satellite receiver (in the bedroom). so i have enough lines for my inputs. since i'm moving into a new house that is pre-wired (all the coax lines go into the master closet), i'm thinking about running another directv/tivo unit for the bedroom - since it is prewired with dual coax connections. so i assume that means i need four lines coming off my dish. however, since i'm having directv come and reinstall a new dish on the new house, my understanding is that the dish is only a triple lnb. is that correct? if so, doesn't that mean, to get my new setup, i'd require a multi-switch? a 3x4 similar to this? http://www.bestbuy.com/site/olspage...d=1076628386020 i'd prefer to buy it from best buy since i get a discount. if it matters, i believe there are four coax lines coming out of the wall on the exterior of the house...but i'm not positive. anyway, if i'm making any sense, please let me know!
