I have used Liberty multiconductor cable, which has worked very well for me (Solid 23 AWG RGBHV COMPOSITE CABLE - NON-PLENUM)
. The product shown on that link isn't exactly the same as what I have used in the past, but I got my cable a couple of years ago and they have changed the lineup slightly. This cable uses a 3-piece connector to make an RCA end out of the cable. I have used it to make component, composite, and S-video (using an adapter cable), and it offers flawless performance when terminated correctly.
The cable is not easy or intuitive to terminate (like standard RG6), and it is only because of my work with home theater installers that I learned how to terminate it myself (trained in person with a Liberty rep).
The cable requires a special stripper that strips the mini cable in sections, along with a crimper specifically designed to work with mini coax. I don't know if it's possible to terminate mini coax using standard RCA fittings, but I've never used a different brand of cable. The mini-coax fittings have a smaller opening, and they are designed to work with the gold-plated pin that is used with the Liberty cables. I could be wrong, but I'm not sure if you can easily mix & match mini cables and standard ends (and
expect to get proper performance/fit).
With all of that said, I'll add that I'm not an expert on anything besides the Liberty brand, so take my comments with that in mind.
