надо найти, где во втором коде присваивается volume стриму и перенести это в первый:

var myVideo:Video = new Video();
	myVideo.height = 537.6;
	myVideo.width = 720.6;
	addChild(myVideo);
 
var netConnection:NetConnection = new NetConnection();
	netConnection.connect(null);
 
var myStream:NetStream = new NetStream(netConnection);
	myStream.play("1.mp4");
 
var transform:SoundTransform = myStream.soundTransform;
    transform.volume = 0;
 
myStream.soundTransform = transform;
 
myStream.addEventListener(AsyncErrorEvent.ASYNC_ERROR, function (event:AsyncErrorEvent):void {}); 
myStream.addEventListener(NetStatusEvent.NET_STATUS, goAgain);
 
myVideo.attachNetStream(myStream);
 
function goAgain (event:NetStatusEvent): void 
{
	if(event.info.code == "NetStream.Play.Stop") 
			myStream.seek(0);
}
