Sorry for all the questions, trying to decide on whether to go with DTV. The house I'm in has had DTV before. It has the slimline dish and 2 coax lines running to one room and one coax running to another room. If I want to install the whole home dvr Genie in one room and one mini in another...all HD...how many coax lines do I have to have running to each receiver? I want the mini wired, not wireless. I assume two to the Genie and one to the mini, just as it is wired now? Thank you for your help!
