Please help me out. I've been away for 6 months and now am about to get reinstalled in my new house. Since the house already has single cable home runs to every room, I'd like to use SWMs so no additional cables have to be pulled to the rooms. I already have 3 HR20-700s and will add one more, along with 2 standard def receivers. I'd like to know exactly what I need SWM-wise to make this all happed? Secondly, what standard receivers do I need to ask for from DTV? Thirdly, exactly what do I need to ask for from DTV, dish-wise etc. to make this all happen? Lastly, the whole hookup of SWMs has me pretty confused, so a detailed explanation of what I'd need along with how to make the connections, would be terribly helpful...and remember, I'm a real dummy about this stuff.
