Video Inside A Movie Clip?

Hi I have this piece of code to put a FLV in my flash movie which works fine until I put the video player inside a movie clip. I can hear the video but can not see the thing?

Any ideas people I new to flash video.

var nc:NetConnection = new NetConnection();
nc.connect(null);

var ns:NetStream = new NetStream(nc);
video1.attachVideo(ns);

ns.play(“video/circuit.flv”);

Thanks in advance.
