请教一个ASP文件中flash播放器上传的问题

Question

请教一下我在一个ASP页面加了一个flash播放器代码是: 
<script type="text/javascript"> 
var s1 = new SWFObject("player.swf","ply","160","120","9","#FFFFFF"); 
s1.addParam("allowfullscreen","true"); 
s1.addParam("allowscriptaccess","always"); 
s1.addParam("flashvars","file=shipin/video.flv&image=shipin/g.jpg; 
s1.write("container");在本地服务器播放挺好的,但一到网上就播放不出来Video not found:shipin/video.flv,请问是什么原因呢,请多多指教谢谢!!!!!!!!
