I thought that my tv was a analog and the channels I get from my cable company are analog also. My setup is a basically a direct cable line to my tv from my provider. My tv only has a Atsc, and ntsc tunner. Will this setup still work anter the chane over or will I have to have at least a clear cam box on each of my tv's. I have about 5 tv that do not have any type of box in the path. All but one of my tv's are from the 90's. Also will my vcr and series 2 Tivo still work. My Tivo is only 1 tunner and it can't do digital.
