Copied from Darth333: s guide:
You can use either the StartNewModule function (if you want an inter-module movie, or the PlayMovie/QueueMovie functions (for intra-module movies)
To play movies during a transition between two modules:
// Send you to the caves on Dantoine after
// playing a video showing the Leviathan
// the movie's name is "05r"
To simply play a movie inside your current module, use:
// usage: PlayMovie( string sMovie );
You can also use the Queue movie script:
//replace FALSE by TRUE if you want it to be skipable when hitting esc.
// usage: QueueMovie( string sMovie, FALSE);
