I am working on a huge iMovie with approx. 50 clips (20 minutes) and everytime i try to manipulate the clips I get an unexpected crash. Is this usual or should I be nervous?

From your description, it sounds like the problem is only in iMovie. One of your files may be corrupted and that might be throwing the wrench in iMovie. As for the best way to take care of this, I can't say, I rarely use iMovie, but I hope it calms your fears a bit.

Have you tried trashing iMovie and reinstalling it with the Software Update?

You might try trashing the plist file for iMovie:

You can find it in your user/Library/Preferences/ folder

Just run a finder search for it and it will pop up.

An unrelated tip: there are lots of multi-languange pdf's in the Documentation folder for iMovie that use a fair amount of hard disk space. If you don't care about having the Chinese version of the iMovie Lessons, these can be trashed too.

I had the same problem with iMovie (fresh install didn't help).

Basically iMovie's stability sucks. Once I got over about 25 clips it would start to crash often. At about 30 clips, every other edit it would crash.

I haven't tried the latest update, but I hear it's still unstable.
