So this is what I like to call a "multipart" question. Currently, I have DirecTV, and two receivers. One in the theater, one in the living room. I'm adding a PVR (MythTV, a lot like Tivo) soon so this is why I'm tailing this out. Here is what I "would" have: 1) Satellite dish has 2 coax lines, one to each Sat receiver. Living room Sat receiver goes out to PVR PVR goes out to TV, Audio Receiver Theater Sat receiver goes out to projector, Audio Receiver Here is what I'm considering: 2) Satellite dish has 2 coax lines, one to each Sat receiver. BOTH Sat receivers are in the living room. BOTH go to two inputs on the PVR PVR output 1 goes out to TV, Audio Receiver PVR output 2 goes under house, into Theater to Projector, Audio Receiver Why would I do this? Because doing #2 would give me two tuners for the PVR, allowing me to record one channel and watch another. It would also allow me to use the PVRs abilities in the theater. My questions: 1) How far can an optical cable (or RCAs, haven't decided if I care about DD for Sat yet) and an S-Video (or VGA, if thats better) cable travel? Are there repeaters of any kind? The theater is about 50 feet away, so will probably need approx 75-100 ft. 2) What is the best way to control the PVR from the movie room? IR to RFs and back to IR? IR Repeaters?
