I just recently purchased a Canon HF S11 camcorder. I shot a bunch of clips in 24p mode. When I try to import on my Mac Pro in iMovie 09, in the import screen, a few clips say Error in red (not importing). The weird thing is, I don't run into any problems importing it on my MacBook Pro. Both are relatively new machines with plenty of hard drive space. I've tried reinstalling iMovie on the Mac Pro and even removing Perian, but still getting the same errors (on the same clips each time). Somebody HELP!!
