I have a camcorder with a little "DV" connector on it. How do I connect it to my computer?
Does your computer have Firewire (IEEE-1394)? That is what you'll need.
The only way to add this to a computer that doesn't have it is by adding an internal PCI or PCI Express cards (for a Desktop) or a PC Card or Express card (for a laptop).
Please see here:
If you have Firewire, you'll just need a cable.
The DV connector on a camcorder is always a "4-pin" Firewire connector. On a Desktop, the connector is typically a 6-pin Firewire connector, although new computers may have the 9-pin Firewire 800 connector.
