Netstream audio playing twice - actionscript-3

Question

I am new to flash (this is the first time I've ever used it or actionscript) and I'm trying to make a video player. The video player gets params from the embed code and pulls the videos from a folder on the server.
I've got the following code (I've removed everything that I'm 100% sure isn't causing my problem):
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;
import flash.events.NetStatusEvent;
import flash.events.MouseEvent;
import flash.events.FullScreenEvent;
import flash.events.Event;
import flash.ui.Mouse;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.text.TextFormat;
import flash.media.SoundTransform;
var nc:NetConnection;
var ns:NetStream;
var ns2:NetStream;
var video:Video;
var video2:Video;
//get filename parameters from embed code
var filename:String = root.loaderInfo.parameters.filename;
var filename2:String = root.loaderInfo.parameters.filename2;
var t:Timer = new Timer(5000);
var duration;
var currentPosition:Number;
var st:Number;
var started:Boolean;
Object(this).mcPlay.buttonMode = true;
Object(this).mcPause.buttonMode = true;
Object(this).ScreenClick.buttonMode = true;
Object(this).mcMax.buttonMode = true;
Object(this).mcSwitcher.buttonMode = true;
Object(this).mcPause.addEventListener(MouseEvent.CLICK,PlayPause);
Object(this).mcPlay.addEventListener(MouseEvent.CLICK,PlayPause);
Object(this).ScreenClick.addEventListener(MouseEvent.CLICK,PlayPause);

stage.addEventListener(MouseEvent.MOUSE_DOWN, resetTimer);
stage.addEventListener(MouseEvent.MOUSE_UP, resetTimer);
stage.addEventListener(Event.ENTER_FRAME, videoTimer);
if (!nc) start();
var IsPaused:String;
function start():void
{
Object(this).slideVolume.maximum = 100;
Object(this).slideVolume.value = 100;

var tf:TextFormat = new TextFormat();
tf.color = 0xFFFFFF;
tf.bold = true;
this.lblTime.setStyle("textFormat", tf);
connect();
t.start();
}
function connect():void
{
nc = new NetConnection();
nc.client = this;
nc.addEventListener(NetStatusEvent.NET_STATUS, OnNetStatus);
nc.connect(null);
}

switch(e.info.code)
{
case "NetConnection.Connect.Success":
if (!started)
{

stream();
}

}
}
function stream():void
{

ns.client = this;
ns.bufferTime = 5; // set the buffer time to 5 seconds
if ((filename2 != null) && (filename2.length > 0))
{
ns2 = new NetStream(nc)
//ns2.client = this; //Uncomment to use ns2 vid for duration info
ns2.bufferTime = 5; // set the buffer time to 5 seconds
startVideo(2);
currentPosition = 1; //Default
ns.seek(0);
ns2.seek(0);
}
else
{
this.mcSwitcher.visible = false;
startVideo(1);
ns.seek(0);
}
}
function startVideo(num:Number):void

}
function ShowControls ():void
{
for (var i:int = 0; i < Object(root).numChildren; i++)
{
switch (Object(root).getChildAt(i))
{
case mcPause:

ScreenClick.y = 154;
}
}
function videoTimer(e:Event):void
{
var curTime = ns.time; //Current time in seconds
var curMinutes = Math.floor(curTime / 60); //Get the minutes
var curSeconds = Math.floor(curTime % 60); //Get the leftover seconds
var durMinutes = Math.floor(duration / 60);
var durSeconds = Math.floor(duration % 60);
//Add the zeroes to the begining of the seconds if it is needed.
if (curSeconds < 10)
curSeconds = "0" + curSeconds;
if (durSeconds < 10)
durSeconds = "0" + durSeconds;
Object(this).lblTime.text = curMinutes + ":" + curSeconds + " / " + durMinutes + ":" + durSeconds;
}
function PlayPause (e:MouseEvent):void
{
switch (IsPaused)
{
case "playing":
IsPaused = "paused";
this.mcPlay.visible = true;
this.mcPause.visible = false;
ns.togglePause();
ns2.togglePause();
break;
case "paused":
IsPaused = "playing";

ns.togglePause();

}
}
The problem I have is small but frustrating (I've spend most of today trying to figure it out with zero progress made). It is thus: Everything works perfectly, except that when the videos load up and play, sound plays twice (for the video that has sound enabled). I am at my wits end trying to figure this out, any help would be greatly appreciated!
Thanks!
EDIT:
Ok, on further research (re-writing every function very simply and seeing if the problem goes away with the features) I've determined that the following function is the root of all evil (or at least my problems):
function startVideo(num:Number):void
{
var startVolume:SoundTransform = new SoundTransform();
startVolume.volume = Object(this).slideVolume.sldVol.value / 100;
if (num == 2)
{
video = new Video(320,180);
video.x = 0;
video.y = 90;
addChild(video);
video.attachNetStream(ns);
ns.checkPolicyFile = false;
ns.play(filename); //path/filename
this.removeChild(btnPlay);
setChildIndex(video,1);
video2 = new Video(320,180);
video2.x = 320;
video2.y = 90;
addChild(video2);
video2.attachNetStream(ns2);
ns2.checkPolicyFile = false;
ns2.play("test.mp4"); //path/filename
setChildIndex(video2,1);
ns.soundTransform = startVolume;
var videoVolumeTransform2:SoundTransform = new SoundTransform();
videoVolumeTransform2.volume = 0;
ns2.soundTransform = videoVolumeTransform2;
ns2.receiveAudio(false);
}
else if (num == 1)
{
video = new Video(640,360);
video.x = 0;
video.y = 0;
addChild(video);
video.attachNetStream(ns);
ns.checkPolicyFile = false;
ns.play("test.flv"); //path/filename
setChildIndex(video,1);
ns.soundTransform = startVolume;
}
IsPaused = "playing";
this.removeChild(btnPlay);
setChildIndex(this.ScreenClick,0);
//setChildIndex(this.mcTitleOverlay,2);
}
I shall persevere with my troubleshooting (I've isolated the problem, hopefully the next step is a solution!
