Grrrr...I still can't get my copy of iMovie to work properly. It really only effects me when it comes to audio editing. The easiest solution until I can afford a new computer is to purchase Quicktime Pro. I'll edit the movies in iMovie, bring them over to my laptop, convert them to AVI using Quicktime Pro, then take them into Windows Movie Maker to put in the music and sound effects. It's an extra step in the process, but right now, the only available option to me. I hate being poor.
