Netstream onStatus and onMetadata problem

[eliana]

Hi
i'm writing a simple player to stream a flv file; video streams fine but the netstream onstatus and the nestream onmetadata are not invoked. Any help?
Here is my code:

var nc:NetConnectio n = new NetConnection;
var ns:NetStream;
var bufferLength:Nu mber = 3;
var fileToPlay:Stri ng;

initCon();

function initCon(){
nc.connect("... .server url...");
fileToPlay = "...filename... ";
}

function initStream(){
ns = new NetStream(nc);
ns.setBufferTim e(bufferLength) ;
objPlayer.attac hVideo(ns);
playFile();
}

function playFile(){
ns.play(fileToP lay);
}

nc.onStatus = function(info:O bject){
trace("LEVEL: " + info.level + " CODE: " + info.code);

if (info.code == "NetConnection. Connect.Success "){
initStream();
}
}

ns.onStatus = function(infoOb ject:Object) {
trace("ns.onSta tus called: ("+getTimer( )+" ms)");
}

ns.onMetaData = function(info:O bject) {
trace("ON METADATA")
}

thanks
