用mediaplayer做视频播放时遇到的诡异问题

 <object id="MediaPlayer" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,0,5,0803"

以上是mediaplayer播放wmv的代码。但是我想用js脚本控制时间跳转。代码如下：
 GetObj("MediaPlayer").controls.CurrentPosition=600;
可是这句代码时而能用时而不能，小弟崩溃了。上来求助，盼望哪位大侠解决了。不胜感激，顿首，鞠躬，再顿首，再鞠躬。

大哥，我现在把代码全贴出来。
这是js 全部的：
 <script language="javascript" for="MediaPlayer">
    function GetObj(objName){
if(document.getElementById){
return eval('document.getElementById("' + objName + '")');
}else{
return eval('document.all.' + objName);
}
}
    function setClickPostion()
    {
      alert(GetObj("MediaPlayer").controls.CurrentPosition);
      GetObj("MediaPlayer").controls.CurrentPosition= 600;
    }
下面是html 全部的：
    <input type="button" id="btnClick" onclick="setClickPostion()" />
        <object id="MediaPlayer" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,0,5,0803"
            type="application/x-oleobject" height="172" standby="Loading Windows Media Player components..."
            classid="clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6" vspace="0" hspace="0" width="210">
            <param name="AutoStart" value="true">
            <param name="AutoSize" value="false">
            <param name="balance" value="0">
            <param name="currentPosition" value="0">
            <param name="enableContextMenu" value="false">
            <param name="enableErrorDialogs" value="false">
            <param name="enabled" value="true">
            <param name="fullScreen" value="false">
            <param name="invokeURLs" value="false">
            <param name="mute" value="false">
            <param name="volume" value="80">
            <param name="playCount" value="1">
                <param name="uiMode" value="none">
            <param name="rate" value="1">
            <param name="URL" value="http://61.158.143.221:8001/Course/video/a123.wmv">
        </object>
出了这些就没别的了。我快疯了。求救呀。

刚好我们也做了个类似的，貌似是下面这句问题，URL地址应该是流媒体服务器的地址吧。
<param name="URL" value="http://61.158.143.221:8001/Course/video/a123.wmv">
下面是我们做的一个实例，你参考下<param name="URL" value="mms://vod.ksedu.cn/dianbo//20100907001-周杰伦.WMV">
