Most likely, you will have to use the S-video (unless your source has component.) As for the audio, you will need to get a converter cable to go from RCA to mini-din (like stereo headphones.) This will cost about 2 bucks at Radioshack. You will have to capture the audio with your soundcard concurrently with the video. It's not impossible to capture audio and video together, but it can be tricky to set up depending on the software you are using. I usually have trouble keeping sync when I do this, so I capture audio and video through my camcorder first using firewire, and then do a separate video capture through my capture card. I can then line these streams up in Vegas, and delete the camcorder video (The DV codec isn't quite as good as the Huffy codec.)
