Analog video to Digital

Do I need a separate software program to capture and
convert analog video to Digital? I have a digital video
camera with an i.LINK jack so I know that I can do it,
but I don't know if the software needed is in XP or not.
My camera directions give me this hook-up: Play the tape;
use an A/V connecting cable into the camera; then out of
the camera to the PC with an i.LINK cable.

If I need extra software, can someone tell me what I need
to look for?
Thank you,
Kaye
