请教哪位高手cctv.com中循环播放flv文件是怎么实现的？
代码：script language="javascript" type="text/javascript">
// <![CDATA[

var ad_count = Math.floor(Math.random() * 15);

flashTagIns.setNew("/homepage/swf/video/video_player.swf?

xmlSrc=/homepage2006/swf/video/tvonlinenewad_" + ad_count + ".xml",

316, 132); // movie path, last two arguments are width and height
flashTagIns.setVersion("8,0,0,0");// default version is "7,0,14,0"
flashTagIns.setWmode('transparent');
flashTagIns.setId('video_player_m');
flashTagIns.write(document);//direct write down, just like

write"<object>" or "<embed>"
//实现窗口失去焦点暂停播放功能
window.onfocus = function () {
try {
getMovieObj('video_player_m').playVideo();
}catch(e){}
};
window.onblur = function () {
try {
getMovieObj('video_player_m').stopVideo();
}catch(e){}
};
//实现窗口失去焦点暂停播放功能 end...
// ]]>
</script>

我把其中的video_player.swf和tvonlinenewad_*.xml都下载了，但在自己的网页

中不能实现呀。
求求哪位大侠帮帮忙。
