Camcorders have a four pin Dvi socket also known as "firewire" for their output, so the cable used has one end with a four pin firewire plug and the other end with either another firewire plug, this being four or six pin to match whatever the computer uses, or the more commonly used USB plug. Less problems are usually experienced using firewire coupling between devices, although in saying that there are always exceptions! A more detailed info link sent via direct e-mail.
