To watch the iMovies, you will first need to download the QuickTime player. If you do not already have this plug-in installed on your computer, you can download it here. Once you have installed the plug-in, simply click on the iMovies and they will play. The iMovies may take up to 20 minutes to load if you have a slow connection. If you would rather save the iMovie right on your computer so you can watch it whenever you like, RIGHT CLICK on the iMovie and select "save target as..."
