/** The Preview feature in Netflix is very nice. 
 ** It's a windows media stream that opens in an embedded player.
 ** But sometimes it's nice to be able to
 ** choose the way it's displayed. This script simply gives you 
 ** a direct link to the source file so you can manipulate it in the
 ** same way you would any media stream, using external players or whatever.
