Why doesn't my flvplayer pause with a class?

1 


class FlvPlayer {
	public var videoURL:String;
	public var theVideo:MovieClip;
	public var nc:NetConnection;
	public var ns:NetStream;
	function FlvPlayer() {
		nc = new NetConnection();
		nc.connect(null);
		ns  = new NetStream(nc);
		
	}
	function playVideo():Void {
		theVideo.attachVideo(ns);
		ns.play(videoURL);
	}
	function rewindVideo():Void {
		trace("rewind");
		ns.seek(0);
	}
	function pauseVideo():Void {
		trace("pause");
		ns.pause();
	}
}

and with


import FlvPlayer.as;

var flvplayer:FlvPlayer = new FlvPlayer();
flvplayer.theVideo = theVideoSkin;
flvplayer.videoURL = "test.flv";
flvplayer.playVideo();
rewindBtn.onRelease = flvplayer.rewindVideo;
pauseBtn.onRelease = flvplayer.pauseVideo;

Now it does play but it doesn’t rewind or pause but i do see the corresponding tracing messages???

Any idea
