[MacDV] iMovie 3 problems related to old projects?

[Doug Mitchell]

I have just run a video I made at Christmas in imovie 2.  It runs just 
fine with no stuttering or anything like that.  There are plenty of 
transitions all of which run flawlessly.  I am running iMovie 3.0.1 on 
a dual 1Ghz machine which perhaps accounts for the difference in 
performance.
