Using SWF and sprites in streaming movies

SWF files and sprites are not streamable, that is, you must create two movies: the streamable movie for the server, and the client movie. The client movie will be placed on an HTTP server, and the streaming movie will be placed on a streaming server. The client movie will contain a URL embedded in the Streaming track that points to the server movie.
