I'm thinking of making the switch to Direct TV after 14 years with Dish. My home has 1 coax cable ran to the basement from each room. I want 2 HD DVR's and 2 HD receivers. I want the whole home MRV. My router is in my office on the 2nd floor where I won't have a tv. I will put one HD DVR on the first floor family room and 1 hd dvr on the first floor bedroom. The other 2 hd receiver's in the bedrooms on the 2nd floor. What is installed at the router to make the MRV work? My router is on a desk across the room from the coax in the wall. Would this be an easy install?
