The problem lies not in the div but in the object tag
strt changing the css from there using !important if required
<video id="wp_mep_2" width="1024" height="576" controls="controls" preload="none" >
<source src="http://www.krissharmsworth.com/test/wp-content/uploads/2013/09/Michael-victor.wmv" type="video/wmv" />
<object width="1024" height="576" type="application/x-shockwave-flash" data="http://www.krissharmsworth.com/test/wp-content/plugins/media-element-html5-video-and-audio-player/mediaelement/flashmediaelement.swf">
<param name="movie" value="http://www.krissharmsworth.com/test/wp-content/plugins/media-element-html5-video-and-audio-player/mediaelement/flashmediaelement.swf" />
<param name="flashvars" value="controls=true&file=" />
</object>
</video>
These controls render at their default height so first change their css then the parent div . Wait ill give a screen shot in some minustes :)
Heres the screen shot i did by changing the styles of the media elements ie the video (silverlight or some thing) and then the above divs.
