embed wmv in WP, IE and FF

I try to embed a wmv file in my blog. IE shows it correct, but with Firefox the whole design of the site and everything get screwed up. Opera does not show the video at all. How can I fix this.

 

What code did you use?

 

<object id="MediaPlayer1" CLASSID="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsm p2inf.cab#Version=5,1,52,701"
standby="Loading Microsoft Windows Media Player components..." type="application/x-oleobject" width="280" height="256">
<param name="fileName" value="http://www.goldtunnel.com/stoningmovie.wmv">
<param name="animationatStart" value="true">
<param name="transparentatStart" value="true">
<param name="autoStart" value="true">
<param name="showControls" value="true">
<param name="Volume" value="-450">
<embed type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaPlayer/" src="http://www.goldtunnel.com/stoning.wmv" name="MediaPlayer1" width=280 height=256 autostart=1 showcontrols=1 volume=-450>

<embed src="http://www.goldtunnel.com/stoning.wmv" width="280" height="256" autoStart="True" uiMode="full" volume="256" mute="false"></embed>
</object>

And also without the embed.

 

I would try:
<embed src="http://www.goldtunnel.com/stoning.wmv" width="280" height="256" autoStart="True" uiMode="full" volume="256" mute="false"></embed>

But, I'm no expert.

 

I tried, but that is not working.
