I’m using a quad with Final Cut Studio 2. I have been capturing successfully from my Sony FX1 for the past year and yesterday, out of the blue, it began locking up when opening the program hooked up to the camera. Both FCP and iMovie do the same thing. The programs lock up and I have to reboot. They open perfectly without the camera. I’ve replaced firewire cables, repaired permissions, tossed preference files and re-installed Final Cut. And it’s not the camera because it works on my older Mac. So I’m at a loss. Anyone have any ideas?
