Need Video/Audio Advice

[homicide94]

I have a Dazzle DVC100 capture card and video distribution amplifier (it has s-video compatibility if it matters) to link my game consoles to my PC and record footage. This all works fine and I get perfect results every single time but I would like to record a second audio track on top of this for live narration, I just need a way to record 1 video and 2 (maybe 3 if I decide I want music in the background) stereo audio tracks simultaneously, preferably using the same program. Buying a mixer isn't really an option, I don't have that kind of money to spend, unless there's a fairly cheap one I don't know about. I want to to record the video and audio from the RCA cables in the DVC100 and the live narration from either my PS3's bluetooth headset or my PC's wireless USB headset, the USB would be easier for me but after the amount of time I've spent on google looking for something like this it really doesn't bother me any more.
