How to use this script:

In this order in the html: 
1. Include 
	<script src="http://fs.net211.com/jwplayer/swfobject.js" type="text/javascript"></script>
	<script type="text/javascript" src="http://fs.net211.com/jwplayer/player2.js" ></script>
2. Define an empty div tag with id= mediaarea + number used for mediaDiv 
	e.g. <div id="mediaarea2433"></div>
3. Enter your text inside a div with id=text + number used for textDiv
	e.g. <div id="text2433"> Text here </div>
4. Within a script tag
   <script type="text/javascript">	
   a. Instantiate the player object. To assure no collision between multiple items on a feed, give the variable a unique name. 
      var p2433 = new n211Player();
	  If you are using the same div number suffix for both the media div and the text div, you can pass the number as a parameter to the object
	  instatiation call as such:
	  var p2433 = new n211Player(2433);
	  if you do this you don't need to set the mediaDivNumber or textDivNumber variables.
   b.  Set your variables as needed. See the full list of variables below:
      p2433.videoFile = 'http://fs.net211.com/vod/media/Video/GCCService/2010-11-14/2010-11-14-Service-rtmp-rss.xml';
	  p2433audioFile = 'http://fs.net211.com/vod/media/Video/GCCService/2010-11-14/2010-11-14-Service-rtmp-rss-a.xml';
	  p2433.podcastFile = 'http://feeds.feedburner.com/GCCService?format=xml';
	  p2433.mediaDivNumber = 100;
	  p2433.textDivNumber = 100;
	c. Load the player
      p2433.player();	
	</script>
You must include at the very minimum the mediaDiv and textDiv tags.
