Video Player Errors

I have made an xml video viewer which works great, however I am getting output errors when I run it- I’m not sure why or what is being affected, but if anyone could help I’d appreciate it.

The errors are as follows:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Here is the code I used:

import fl.transitions.TweenEvent;

var flvControl = mc_all.mc_Loader.movieLoader;

var vidTitle:Array = [];

var thumbList:Array = [];

var fadeIn:Tween;

var vidIndex:Number = 0;
var b:Number = 0;
var c:Number = 0;
var xSpacing:Number = 140;
var ySpacing:Number = 97;
var xs:Number = 0;
var ys:Number = 0;
var thumbRowCount:Number = 2;
var myFont:Font = new Font1();
var textFormat:TextFormat = new TextFormat();
textFormat.font = myFont.fontName;
textFormat.italic = true;
textFormat.size = 10;

btnPlay.buttonMode = true;

var xmlURLLoader:URLLoader = new URLLoader();
var xmlURLRequest:URLRequest = new URLRequest( "gallery.xml" );
xmlURLLoader.load( xmlURLRequest );
xmlURLLoader.addEventListener(Event.COMPLETE, sortTheXML);

function sortTheXML(event:Event):void {
	var xmlData:XML = new XML( xmlURLLoader.data );
	var a:Number = xmlData.video_path.length();

	while ( b < a ) {
		vidList.push(xmlData.video_path**);
		vidTitle.push(xmlData.video_title**);
		vidDesc.push(xmlData.video_desc**);
		thumbTitle.push(xmlData.thumb_title**);
		thumbList.push(xmlData.thumb_path**);
		b = b + 1;
	}
	flvControl.bufferTime = 3;
	flvControl.source = vidList[ vidIndex ];
	text_mc.vidTitleBox.text = vidTitle[ vidIndex ];
	text_mc.vidDescBox.text = vidDesc[ vidIndex ];
	fadeIn = new Tween(text_mc, "alpha", None.easeNone, 0, 1, .5, true);




	loadTheThumbs();


	function loadTheThumbs() {

		var thumbLoader:Loader = new Loader();
		var thumbRequest:URLRequest = new URLRequest( thumbList[c]);
		thumbLoader.load( thumbRequest );
		thumbLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, whenThumbsLoad);


		function whenThumbsLoad(event:Event):void {
			var thisThumbsLink:String = vidList[ c ];

			thumbLoader.x = (xs * xSpacing) + 26 ;

				xs = 0;

					text_mc.vidTitleBox.text = thisPicsTitle;
					fadeIn = new Tween(text_mc, "alpha", None.easeNone, 0, 1, .5, true);
				}



			}
			
			
			all_thumbs.addChild( thumbLoader );
			all_thumbs.addChild( thumbTitleBox );
			all_thumbs.addChild( Play );
			
			
			c = c + 1;
			if (c < a ) {
				loadTheThumbs();
			}
		}
	}
	flvControl.playPauseButton = btnPlay;
	flvControl.seekBar = btnSeekBar;
	flvControl.volumeBar = btnVolumeBar;
	flvControl.bufferTime = 3;

}

this.addEventListener(Event.ENTER_FRAME, updateNP);

function updateNP(event:Event):void {


	// time code code...
	var totalSeconds:Number = flvControl.playheadTime;
	var totalSeconds2:Number =  flvControl.totalTime;
	var minutes:Number = Math.floor(totalSeconds /60);
	var minutes2:Number = Math.floor(totalSeconds2 /60);
	var seconds = Math.floor (totalSeconds) % 60;
	var seconds2 = Math.floor (totalSeconds2) % 60;
	if (seconds < 10) {
		seconds = "0" + seconds;
	}
	if (seconds2 < 10) {
		seconds2 = "0" + seconds2;
	}
	timeBox.text =  minutes + ":" + seconds + " / " +  minutes2 + ":" + seconds2;
	timeTotalBox.text = minutes2 + ":" + seconds2;

}

Thanks in advance!
