Cannot play FLV file from FMS2

Hi there!
Well I am going nuts with this issue!
I am using Flash Media Server 2 on a Web Server.
I have the following folder structure on the FMS for my application.
aplications/casino/casino.flv
aplications/casino/casino.asc
also:
aplications/casino/definst/casino.flv
aplications/casino/definst/casino.asc
the *.asc files are empty.
I haven’t made any other configuration on the FMS.
Now, I am trying to play the flv file using the following script:

var nc:NetConnection = new NetConnection();
nc.connect(“rtmp://xxx.xxx.43.66/casino/definst”); //xxx symbols are used for security
nc.onStatus = function(infoObject:Object) {
if (infoObject.code==“NetConnection.Connect.Success”){
var ns:NetStream = new NetStream(nc);
myVideo.attachVideo(ns);
ns.play(“casino.flv”);
}
};
the connection never fails but the video stream doesn’t start
What am I doing wrong?
Best Regards,
Olie
