If you open the preferences in iTunes there is a check box under one of the tabs that says something like "copy media to iTunes library." If you uncheck that and then drag the movies to your iTunes library the items will show up but not be stored inside your library. As long as your AppleTV can see your iTunes library, always have to have iTunes open, you can stream the movies. Hope this helps.
