well, sorry no suggestion for you, cause unfortunately i'm having the same frustrating problem. I've got deadlines to meet and Final Cut all of the sudden stopped capturing from my MiniDV Canon Elura 100. And it is doing the same exact thing that you described, everytime I go to Log and Capture something, Final Cut locks up, but when I unplug the FW cord its ok. But still won't capture. What the heck is wrong with this? I thought this was a widespread problem and that Apple would put out an update to fix it, but you are the first person I've seen that has had this same exact problem. Any suggestions or help would be greatly appreciated. Thanks.
