[MacDV] iMovie 3 problems related to old projects?

[Shirley Kehr]

I brought up a 26-minute movie on my dual 500 and started playing it. I
didn't see any of this slow down, but I did hear some little sounds I
didn't think were there before (like a little electronic noise made by a
watch). I'll have to move it to the iMac which still has iMovie 2 and
see how it plays there I guess.

I'm wondering if these problems are showing up mostly on G3s, but then
you do have a G4 also, so maybe iMovie 3 is taking advantage of dual
processors and gave up something on single processors? Guess I could
test that too by taking it to work where there is a single 500 G4 tower.
