Hi, I do use iMovie5+6 under 10.4 and 10.5 mostly, but from time to time I get back to my iMac G3 DV and iMovie3 under 10.2 and capture there, for certain reasons. It has worked before, but now, all of a sudden, I can't write movies to an external drive, anymore, while they are captured. It works to capture to the internal drive but not external. I repaired permissions. Any other ideas, please???
