Looping .FLV

I have a short .flv I'm running and I need to loop it. Any ideas on how to do it? Thanks

/this the code to play the videos
var nc3:NetConnection = new NetConnection();
nc3.connect(null);
var ns3:NetStream = new NetStream(nc3);
theVideo3.attachNetStream(ns3);
ns3.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler2);
function asyncErrorHandler2(event:AsyncErrorEvent):void
{
// ignore error
}
ns3.play("VietnamRiver.flv");
