请教embed被嵌套在object里做播放.wmv的兼容性写法

目前我会两种实现在线播放.wmv文件的格式，

一是object:
HTML code

<!--<OBJECT id="WMP" height="290" width="290" classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6" VIEWASTEXT>
<PARAM NAME="URL" VALUE="http://www.xxx.com/xx.WMV">
<PARAM NAME="rate" VALUE="1">
<PARAM NAME="balance" VALUE="0">
<PARAM NAME="currentPosition" VALUE="0">
<PARAM NAME="defaultFrame" VALUE="">
<PARAM NAME="playCount" VALUE="1" >
<PARAM NAME="autoStart" VALUE="-1">
<PARAM NAME="currentMarker" VALUE="0">
<PARAM NAME="invokeURLs" VALUE="-1">
<PARAM NAME="baseURL" VALUE="">
<PARAM NAME="volume" VALUE="50">
<PARAM NAME="mute" VALUE="0">
<PARAM NAME="uiMode" VALUE="full">
<PARAM NAME="stretchToFit" VALUE="0">
<PARAM NAME="windowlessVideo" VALUE="0">
<PARAM NAME="enabled" VALUE="-1">
<PARAM NAME="enableContextMenu" VALUE="-1">
<PARAM NAME="fullScreen" VALUE="0">
<PARAM NAME="SAMIStyle" VALUE="">
<PARAM NAME="SAMILang" VALUE="">
<PARAM NAME="SAMIFilename" VALUE="">
<PARAM NAME="captioningID" VALUE="">
<PARAM NAME="enableErrorDialogs" VALUE="0">
</OBJECT>-->

2是embed:

HTML code

<embed src=http://www.xx.com/xxx.wmv controls=imagewindow,controlpanel,statusbar width=440 height=350 autostart=1 loop=-1>

但是这两种方式遇到了兼容性问题，在网上查了一下，说是用object嵌套embed可以实际多浏览器兼容，但是在下的水平不够，不知如何实现，还请各位不吝赐教。
