为什么不能接受到SendPlayStateChange事件呢？
<OBJECT ID="player" WIDTH="400" HEIGHT="100" CLASSID="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95" >

if(MediaPlayer.SendPlayStateChange)
{
//你想要执行的代码
}
else{
////你想要执行的代码
}

直接写这样一个函数就可以

function MediaPlayer1::SendPlayStateChange(){
//事件处理代码
}

很简单的嘛:
<SCRIPT LANGUAGE=javascript FOR=MediaPlayer1 EVENT=SendPlayStateChange(参数...)>

</SCRIPT>
把上面的加入到包括MediaPlay控件的网页中,参数要对应哦!而且应该放在控件定义后面!WMPSendPlayStateChange()中就加入你要额外执行和代码!
这只是事件响应哦,像该控件的右键菜单替换就比较罗嗦一点!
