.....neither end fits my computer or camcorder....
Look in the documentation for your camcorder.
Is your camcorder a DV camcorder?
Does it have a spot to plug in a small 4 pin 1394 cable?
If not, you can't capture video whith firewire.
Is it an old style High-8 or VHS?
Does it only have a connector for analog out or S-video?
Does the motherboard have onboard 1394 support or do you
have 1 1394 card in on of the PCI slots?
What type of computer do you have? when you look at all
the places to plug cables in, can you find a plug that
matches the shape as the firewire cable?
If you have a 4>6 pin cable, and there's no place on your
camera or computer to plug it in, it would seem you don't
have a DV camera and your computer doesn't have firewire
support. (no card installed...)
