Are you talking about a laptop or desktop computer? What OS are you running? If you have the room, as was suggested above, buy a firewire card. If all you have is USB ports and no room to add a firewire card then you will need a capture device that has a firewire port on it. If the camcorder did not record in HDV then you could get a capture card without a firewire port and use the analog out cable to connect to a capture device. Knowing the make and model of the camcorder would help.
