External FLV playback...please help!

1

I’ve read two tutorials (including one from Adobe) and followed their instructions directly. I’ve got an FLV video (sabre.flv) in the same folder as my SWF, an ActionScript-controlled video object called theVideo on stage, and the following code:

var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream();
theVideo.attachVideo(ns);

ns.play("sabre.flv");

When I publish my movie or open the published SWF, I get nothing. Please tell me what I’m doing wrong!

Thanks,
Steve
