Could someone help with XML driven video player?

I created an FLV player using a tutorial. The player is XML driven, so that when I click on the next button, the next video in the XML list plays.
The problem is that I don’t want to do it this way. I want to have some thumbnail images on the side of the player representing each video, and when clicked the appropriate video plays.

The XML AS looks like this:
var videoList:XML = new XML();
var loader:URLLoader = new URLLoader();
var req:URLRequest = new URLRequest(“playlist.xml”);
loader.load(req);

loader.addEventListener(Event.COMPLETE, completeHandler);
function completeHandler(evt:Event):void {
videoList = XML(evt.target.data);
ns.play(videoList.video[currentVideo].@file.toString());
resumeVideo();
};

Can someone help me with this?
Thanks.
