First, let me apologize, I am very new at this. I have been able to use the JW FLV player successfully on my site. I don't really know anything about xml, so I wanted to use the javascript playlist. I installed the 3 files the tutorial says to put on the server, and edited the script with the correct file locations and added those parts to my html, but when I bring up the page, all I see is the player, no playlist. I don't know if I'm missing something or what. Is there somewhere I should be entering the filenames, etc. of the flv files I want to show up in the playlist?
Here is the section of the html for the player and playlist:
<center>
<script type="text/javascript" src="http://www2.umaine.edu/MarchingBand/videos/2009/jquery.js"></script>
<script type="text/javascript" src="http://www2.umaine.edu/MarchingBand/videos/2009/jquery.playlist.js"></script>
<link rel="stylesheet" type="text/css" href="http://www2.umaine.edu/MarchingBand/videos/2009/playlist.css" />
<script type='text/javascript' src='http://www2.umaine.edu/MarchingBand/videos/2009/swfobject.js'></script>
<div id='mediaspace'>This text will be replaced</div>
<script type='text/javascript'>
var so = new SWFObject('http://www2.umaine.edu/MarchingBand/videos/2009/player-viral.swf','mpl','470','320','9');
so.addParam('allowfullscreen','true');
so.addParam('allowscriptaccess','always');
so.addParam('wmode','opaque');
so.addVariable('author','University of Maine Marching Band');
so.addVariable('title','UMaine Alumni Band Halftime Show');
so.write('mediaspace');
</script>
Thanks for any help.

There's a working implementation here: http://willswonders.myip.org:8074/JavaScript%20Playlist.html
If you want the two files that I'm using, they are here:
