I'm moving in with my girlfriend who has a condo and its been years since I've have Directv installed. I have two HR-24 dvr's that I'll be bringing with me. She has existing coax cable for cable tv in the locations that I'll be putting my dvr's. I figure I'll upgrade to the whole home dvr if I can. Do I still need two coax lines run for each dvr? The living room won't be a problem. Its a straight drop to the basement but the upstairs room is where I think I'll run into problems. It looks like to me when they first built the condo that the coax cable instead of dropping from the room to the basement on an interior wall, goes up, through an attic space and down and exterior wall to the basement. Seems like it would be real tough to run coax again. So I was hoping just to use the existing coax in that room. Can that be done?
