I'm just about to start pre-wiring our new house with both home theater and structured wiring. We are going to have a TV niche over the fireplace and put the A/V rack in a built-in cabinet on a perpendicular wall. I'm planning to run both s-video and composite from the A/V rack to the niche. Is there any reason why I can't assemble the composite cables myself? I'd like to avoid drilling holes any larger than I have to in order to get the connectors to pass through. It seems that the component video cables could be made up with RG-6. The only problem seems to be how to terminate them. A quick google search uncovered several adapters for converting an F connector to a male RCA. But I haven't found any direct RCA connectors for RG-6 coax. Would the adapters work? Or even better is there a source of RCA connectors for RG-6?
