Esto es lo que tengo yo en mi web:
<object id="MediaPlayer"
classid="CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95"
codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,5,715"
standby="Loading Microsoft Windows Media Player components..."
type="application/x-oleobject" width="200" height="150">
<param name="FileName" value="../videos/multimedia.wpl">
<param name="showcontrols" value="0">
<param name="showdisplay" value="0">
<param name="autosize" value="1">
<param name="showstatusbar" value="0">
<param name="autostart" value="1">
<param name="Loop" value="20">
<embed type="application/x-mplayer2"
pluginspage="http://www.microsoft.com/isapi/redir.dll?prd=windows&sbp=mediaplayer&ar=Media&sba =Plugin&"
src="../videos/multimedia.wpl" width="200" height="150" showControls="false" showdisplay="false" showstatusbar="false" autosize="1" autostart="1" loop="5">
</embed></object>
