Flash 8 and FMS 3.5 problem

Hi,

I have a little Flash 8 FLVPlayback-based video player, designed to read a list of video URLs (pointing to a demo version of FMS 3.5) from XML. The player works the first couple of times you select a video but then stops displaying anything when you select more videos. The seek bar seems to move but there is not picture or sound. You can see it here:

Test player

My ActionScript is as follows:

var vidList:XML = new XML();
vidList.ignoreWhite = true;

vidList.onLoad = function() {
//populate array from XML
var videoArray:Array = this.firstChild.childNodes;
//iterate array and add videos to the listbox
for (var i = 0; i<videoArray.length; i++) {
videoList.addItem(videoArray .attributes.desc, videoArray.attributes.url);
}
//XML loaded, so play first video
myPlayer.play(videoList.getItemAt(0).data);
textUrl.text = videoList.getItemAt(0).data;
videoList.selectedIndex = 0;
};

var vidListener:Object = new Object();

vidListener.change = function() {
myPlayer.play(videoList.getItemAt(videoList.selectedIndex).data);
textUrl.text = videoList.getItemAt(videoList.selectedIndex).data;
};

videoList.addEventListener("change", vidListener);
vidList.load("videos.xml");

Can anybody help!?

Thanks!
