I just purchased a Cannon Optura 40 refurbished from Cannon. I have recorded some footage and taken a few still photos. When I use the usb the still photos import just fine. When I connect with firewire, the computer does not recognize the camera. I followed imovie's troubleshooting tips, I repaired permissions, restarted my computer, and tried the camera with two other macs with the same result. I don't know if I might be missing something with the set up or if I got a faulty camera. I am using imovie 6.0.3 and quicktime 7.1.3 on a powermac dual 2.7 g5 with 2.5 gigs of ram Any help would be greatly appreciated.
