Hmm ... looks like that one does not easily interface with a computer. It does not have a USB cable; it has, rather, a special cable that is not so often seen (And rarely seen on a computer). The only way I can see for you to get video from this to a computer is to do one of two things:
Purchase a TV tuner for your computer and hook up the audio/video out cables from your camera to it. Then use the software that came with the card to record it that way (By playing the video on the camera and thus sending it to the computer via the A/V cables.
Use a DVD player that can record DVDs. You'd do the same thing as above, connecting the A/V cables to the DVD recorder and playing it as the recorder records. You could then put the DVD into a suitable DVD drive on your computer and get it off of there. I am not positive of how you'd do that; depends on how the burner works.
Alternatively, buy another MiniDV camera that does have a USB cable, put the tape in that camera, connect it to your computer, and then record the original way I hinted at.
