// IlsInlineMedia(sPath, nWidth, nHeight, bShowControls, bAutoStart, nRepeat)
//		sPath:			Path, relative to the page that invokes this function, of the media file to be played.  Supports .wmv, .wma, and other file types.
//		nWidth:			Width, in pixels of the media to be played.
//		nHeight:		Height, in pixels, of the media to be played (not counting the controls bar displayed by Windows Media Player)
//		bShowControls:	true iff the controls bar should be displayed beneath the media.  If this value is false, "bAutoStart" should be true; otherwise, there will be no way to play
//						the media.
//		bAutoStart:		true iff the media should start immediately playing.  Take care if this value is false, because Netscape 8.1 (and perhaps other versions of Netscape?) appears to
//						have a bug where when this value is false, the video displays as blank.  IE 7.0, Firefox 2.0.0.3, and Opera 9.2 do not have this bug.
//		nRepeat:		If a positive integer, this is the number of times the media will repeat.  If -1, the media will repeat "forever."  Do not use zero, as its behavior is
//						not documented.
//	returns:	Nothing
//
// Displays a media file (video, music, etc.) using Windows Media Player at the place in the HTML file where this function is invoked.

		// here, as instructed.  Note that with this particular "classid", we are actually asking Windows Media Player to simulate version 6.4 of the player, rather than a later version,
		// so that this page will run even with an old version of Windows Media Player.
