Looping XML video playlist

I’ve pieced together an XML driven playlist for videos. Only thing I can’t figure out is how to play the playlist continuously. When the last video ends, I want it to start with the first video and run through the playlist again and infinite number of times. I can only get the last video to restart when it finishes instead of going back to the first video.

Much appreciation for any help in resolving this mineute issue. I included my AS below.

// The amount of time between calls to update the playhead timer, in milliseconds.
var updatePlayheadInterval:uint = 10;

// The client object to use for the NetStream object.
var client:Object;

// The index of the currently playing video.
var idx:uint = 0;
// A copy of the current video's metadata object.
var meta:Object;
var nc:NetConnection;
var ns:NetStream;
var playlist:XML;
var t:Timer;
var xmlLoader:URLLoader;
var vid:Video;
var videoXML:XMLList;
// Initialize the xmlLoader variable which will be used to load the external playlist XML file.
xmlLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlCompleteHandler);
xmlLoader.load(new URLRequest("xml/videos.xml"));

// Once the XML file has loaded, parse the file contents into an XML object, and
// create an XMList for the video nodes in the XML.
function xmlCompleteHandler(event:Event):void {
    playlist = XML(event.target.data);
    videoXML = playlist.video;
// The main application.
function main():void {
    stage.align = StageAlign.TOP_LEFT;
    // Create the client object for the NetStream, and set up a callback handler for
    // the onMetaData event.
    client = new Object();
    client.onMetaData = metadataHandler;

    nc = new NetConnection();

    // Initialize the NetSteam object, add a listener for the netStatus event, and set the
    // client for the NetStream.
    ns = new NetStream(nc);
    ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
    ns.client = client;

    vid = new Video();

    // Begin playback of the first video.

    // Initialize the Timer object and set the delay to updatePlayheadInterval milliseconds. 
    t = new Timer(updatePlayheadInterval);
    t.addEventListener(TimerEvent.TIMER, timerHandler);

// Event listener for the ns object. Called when the net stream's status changes.
function netStatusHandler(event:NetStatusEvent):void {
    try {
        switch (event.info.code) {
            case "NetStream.Play.Start" :
            //If the current code is Start, start the timer object.
            case "NetStream.Play.StreamNotFound" :
            case "NetStream.Play.Stop" :
            // If the current code is Stop or StreamNotFound, stop the timer object and play 
            // the next video in the playlist.
    } catch (error:TypeError) {
        //Ignore any errors.

// Event listener for the ns object's client property. This method is called when
// the net stream object receives metadata info for a video.
function metadataHandler(metadataObj:Object):void {
    // Store the metadata information in the meta object.
    meta = metadataObj;
    // Resize the video instance on the display list with the video's width and
    // height from the metadata object.
    vid.width = meta.width;
    vid.height = meta.height;
    // Center video instance on Stage.
    vid.x = (stage.stageWidth - vid.width) / 2;
    //vid.y = (stage.stageHeight - vid.height) / 2;            

// Retrieve the current video from the playlist XML object.
function getVideo():String {
    return videoXML[idx][email protected];

// Play the currently selected video.
function playVideo():void {
    var url:String = getVideo();

// Decrease the current video index and begin playback of the video.
function playPreviousVideo():void {
    if (idx > 0) {

// Increase the current video index and begin playback of the video.
function playNextVideo():void {
    if (idx < (videoXML.length() - 1)) {
        // If this is not the last video in the playlist increase the video index
        // and play the next video.
    } else {
        // Instruct what to do after end of last video is reached.

// Event handler for the timer object. This method is called every
// updatePlayheadInterval milliseconds as long as the timer is running.
function timerHandler(event:TimerEvent):void {
    try {
        } catch (error:Error) {
            // Ignore this error.
