This is killing me. There are two ways to export movies in iPhoto 5, one is to create a slide show and export it, and the other is to select photos or an album, and click on share and it gives you the option to export the photos, a website, or a quicktime movie. It has the option to "add currently selected music to movie"... for the love of me I can't figure out how to choose the piece of music to use... right now it's not including anything when it exports it. I can choose the music with the slideshow fine and that exports... I feel dumb, help!
