HTML5 Video With Flash Fallback

This page demonstrates Firefox 3.6 and Opera 10.5 failing to display fallback content when MP4 video is not supported. This particular example uses the following HTML:

<video id="orders-video" width="480" height="360" controls>
	<source src="/video/orders.m4v"></source>
    <object data="/video/mediaplayer/player.swf" type="application/x-shockwave-flash" width="480" height="360">  
        <param value="/video/mediaplayer/player.swf" name="movie"/>  
        <param value="file=/video/orders.m4v" name="flashvars"/>
    </object>
</video>
