Using WMP 11 as an external player (1 Viewer)

[thebalance]

I want to use WMP11 as an external moive player but I cannot identify a command line option to automatically close when a movie has finished - /close appears to have existed on previous versions and is available for media sharing but not as a standard option (I've tried & it does nothing).

Does anyone know how to make WMP close when finished playing please.
