This cable looks like it won't fit. While the one end looks like it'll fit in the iMac, I need the other end to be a DV plug for the camcorder. I can't plug the firewire 400 into my camera, that's what I used to plug into the Powerbook.
But this should be helpful. At least I know now that the iMac's have Firewire 800 ports. So I'll look for a DV to firewire 800 cable. Thank you.
