You need either a digital camcorder or a video capture card. I just bought a Dazzle capture card today and it works pretty nice. I'm in the process of making a vid right now.
Circuit City has the DVC80 for $29.99 after the rebate. That's a hell of a price and it will sell quick. I should know since I work there and we sold out today, lol. Glad I grabbed mine in the morning and set it aside.
