What you need is ...
DV cable
Firewire card
And adobe premier 6.5 / windows movie maker
Could be if your running windows 2000 or earlyer, XP seams to just get on with it and find any thing u jam in.
Me and Fatmike had this problem he had had the camera for around a year never been used to capture footage, so we got it round mine pluged it in and no luck .
Pluged my camera in and it worked turned out his dv plug was broken.
Could of happened to yours ??
Try it in a mates pc if no luck go to a camera shop and get them to check it out.
