as3加载flv视频格式后能自动暂停么？

var videoConnection:NetConnection = new NetConnection();  
    videoConnection.connect(null);  
       var videoStream:NetStream = new NetStream(videoConnection);  
       videoStream.play("P1040107.flv");  
       var video:Video = new Video(100,70);//可设定大小
       video.attachNetStream(videoStream);  
       video.x = (Math.floor(i/4))*120+10;
       video.y = (i%4)*80+10;       
       addChild(video);
想让他一加载就自动暂停，怎么弄啊？弄了半天我搞不定！

videoStream.pause();
