/*
 *	media-play-wmv.js  - GridNetworks Javascript library supporting 
 *                         the simple playing of media using Windows
 *                         Media Player in both embedded and standalone
 *                         mode.  
 *						
 *	NOTE:  This library is provided both as a "default" 
 *    implementation, used in our "white label" 
 *    download/install/verify/play implementation, and as a start
 *	in developing your own specialized functions to support more 
 *    complex web experiences.
 *	
 *	For most purposes, this library will not require any 
 *    customization or change	beyond assigning the variables defined at 
 *    the top of the file.  For additional information about changing
 *    or adding to these functions, consult the GridNetworks Javascript
 *    API documentation on the GridNetworks Customer Portal.
 *	
 *	
 *	THE FOLLOWING VARIABLES MUST BE CUSTOMIZED ON A PER-CUSTOMER     
 *    BASIS:   
 *	
 *		The "defaultCustomerMediaLibrary" variable is used in the 
 *		one-argument form	of both launchMovie() and playMovie().
 *		If you are mixing media on the same	page or site from 
 *		multiple media libraries, then you'll need the two-argument
 *		form, passing in both the media lookup key and the media
 *		library.  
 *	
 *		In general, each customer account will have an 
 *		"assignedGCRAddress", so this	does not need to be passed
 *		around; it merely needs to be assigned here so it
 *		is properly used in each of the following functions.
 *
