It's actually kind of funny, if you want just a .mov file for iDVD/iMovie, you can simply open the .avi file in quicktime (make sure you have divx or 3ivx installed), and then select 'save as..' instead of export, the default save is a .mov. It doesn't actually convert the file, but somehow makes it compatible with anything requiring .mov. I usually save it with dependencies so it comes out to less than a meg in size (but you need to keep the original .avi around). One thing I am not sure about is if this works without quicktime pro... never tried it without. Maybe someone else can give it a shot.. Also..maybe just changing the .avi to .mov extension in finder has the same effect (as long as the correct codecs are installed)? Didn't think of trying it before!
