sadlersmead, this post is not really aimed at you
I seem to remember an old portable TV of mine that had a similar set up, but this was quite some time ago and standards have now changed.
I just really wanted to post to ensure that this thread isn't confused with the more standard set up you get now days where a single 3.5mm jack (normally labelled AV out) feeds stereo audio and a video signal to three seperate connectors. This cable is normally supplied with the camcorder.
