Hello could you help me with preloading a netstream,cant get this to work,my code for the netstream is:

//Netstream code
maConnexion=new NetConnection();
maConnexion.connect(null);
monFluxVideo=new NetStream(maConnexion);
maVideo.attachVideo(monFluxVideo);
monFluxVideo.play(“Flv_files/”+_root.moviestatus+".flv");
//loop the video
monFluxVideo.onStatus=function(infoObject){
if(infoObject.code==“NetStream.Play.Stop”){
monFluxVideo.seek(0);
monFluxVideo.play();
}
};

Thanks
