The IMoaDrMovieStage interface provides access to new stage-related functions associated with a movie.
IMoaDrMovieStage is an additional interface on the same movie class that supports IMoaDrMovie and IMoaDrMovie2.
You acquire a movie interface by calling the IMoaDrPlayer methods GetActiveMovie()
or GetNthMovie(). This returns to you an IMoaDrMovie interface.
You can call the QueryInterface method off this interface to retrieve an IMoaDrMovieStage interface.
This interface was added with Director 7.
