I provide the user-interface for playing MPEG movies, including play/stop/rewind buttons and volume and position sliders. To create an instance of me, evaluate:

MPEGMoviePlayerMorph new openInWorld

Then use the "open" button to open an MPEG movie file. This class supplies the front panel; the real work is done by MPEGDisplayMorph and StreamingMP3Sound.

	descriptionForPartsBin If the receiver is a member of a class that would like to be represented in a parts bin, answer the name by which it should be known, and a documentation string to be provided, for example, as balloon help. When the 'nativitySelector' is sent to the 'globalReceiver', it is expected that some kind of Morph will result. The parameters used in the implementation below are for documentation purposes only!
