An S-video cable should work as a standalone option.
As for software there is a lot of options. I would try Windows Moviemaker first as it's a free app you can download from their site. You may even have it on your system. It's basic as an edit tool but works with a lot of different cameras, which is handy.
I've got Premier pro CS3 myself but don't like it that much. That said, as long as the capture part of the app is triggered by the S-video it will do a good job. The only way to find out is to try it and again it will cost nothing. I use Pinnacle studio stuff as it has a lot of functionality, is easily upgraded and I just find it more user friendly.
I did wonder if one of the Dazzle capture cards from Pinnacle (or a similar capture card from a reputable supplier) would solve the problem, but it has a standard scart output (3 jacks/yellow, white red). It might actually do the job given that the cam itself is only outputting to two channels anyway but I couldn't be certain on that.
I'm not being as helpful as I'd hoped but it's tricky without knowing the camera properly. At least one of the above should capture the output one way or another. If the free options can't be made to work then an AV compatible capture card is probably the most hassle free way of doing it, rather than hunting for custom cables and so on.
