I have an older "stereo" TV, it has cable input, 3-way RCA jacks, and ext. speaker jacks. I have a digital cable box, Home Theater system(new), a newer DVD player, and a newer VCR. In order to run DVD, I have a small "RF" modulator. I am simply trying to hook all together, and unable to get everything going. I have RCA jack cords, plus the newer type "S" video cord(s), and also an "optical" video cord. OK, from digital cable box (has cable wire from outside in input) where does the output cable wire go?(bear with me). Into the theater system?. I'll try and make this easier, I was told all wires go into the theater system, then to TV (utilizing cable jack, RCA jacks, and external speaker jacks back to home theater system?). Am I hooking things redundantly (twice) using RCA jacks, and also "S" video cords both?
