Sure, feel free. I definitely learned a lot and there are a few things I would do differently. I will say that the DTV genie system is really nice (although this probably isn't the thread to discuss that ), although you are limited as to how many boxes you can have (4 total). You will want to run homerun RG6 for both the DTV and cable internet installers. It made both installations super easy that they didn't have to wire into the house.
Yeah, I already use the Genie system. Just the wife, kid and I, so the 4 isn't a problem, as I just plan on splitting the rooms they are used in, since I don't see a case where we'd want more than 4 different things on. Like right now, I have one going to my room, bath room, and outside tv. Another used for office and Kitchen tvs, and my kid's room and the Living room have one each. Using IR repeaters and hdmi splitters and long hdmi runs currently.
