Video camera usage

I am trying to copy video from the video camera to my computer, on my
last laptop (it had XP Professional Service Pack 2) everything worked
fine, but now with Vista, in Windows movie maker I get an error that
says "Import video could not find a compatible digital video device." I
have checked the connects and made sure the camera is in proper mode,
but still nothing is detected. Is there some way I can expand the
compatibility of my system to detect my camera so I can use it?
