Ok. Got a new Canon Optura 10. Took some movies. I have 10.2.6. Have the newest iMovie. Got the 4 pin to 6 pin FireWire cable. But when I plug in the camera to the computer, I get nothing. Nothing mounts, and I don't see a way to import any movie or images. Do I need software or anything? The video thing is way new to me. Thanks in advance for help.
