I used to make videos with a DV cam, & to hook the camera's rca cables to the computer I used a special graphics card with a dongle hanging out of it.
HERE'S A DONGLE FOR A BUCK
Basically, if the camera has rca inputs that match the red/white/yellow plugs (or the black one), AND the back of your pc has an open slot that looks like the other end of the dongle, you should be good. Just find some free video capture software & you should be in business. Let me know if you need more than that.....send me a PM or we'll start a thread. Video is what I do.
Also, if your camera has firewire & so does your pc, you should be ready to go. Plug one into the other, turn it on, & a window should pop up telling you what's next. The newer the technology, the easier it gets.
