iGetMovies allows you to copy a QuickTime movie from the iTunes Music Store or a movie or audio file from Safari to your Desktop. Once iTunes or Safari has loaded completely a movie, click on the button of iGetMovies and it will copy it/them to your Desktop. It depends on the website, but it works most of the time. It has been done with AppleScript Studio. My website is in french for the moment, but the applications are also in english.
