Usually, when inserting a media file (like wmv) the html code looks like this:

<object codebase="http://activex.microsoft.com/activex/ controls/mplayer/en/nsmp2inf.cab#Version=6,0,02,902" type="application/x-oleobject" height="375" standby="Loading Microsoft Windows Media Player components..." width="500" classid="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95">
<param name="FileName" value="http://media.SITENAME.com/uploads/users/bobsmith/9 Yogananda PS.wmv"       />
<param name="autoStart" value="1"       />
<param name="showControls" value="1"       />
<param name="showstatusbar" value="0"       />
<param name="windowlessvideo" value="false"       /><
<embed name="MediaPlayer1" src="http://media.SITENAME.com/uploads/users/bobsmith/9 Yogananda PS.wmv" autostart="1" showcontrols="1" showstatusbar="0" windowlessvideo="false" width="500" height="375" type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaPlayer"   ></embed>
    </object></

 

However, when inserting this file, the param tags (highlighted in red) are not written and hence the resulting html looks like this:

<object style="left: 0px; width: 640px; top: 1347px; height: 525px" codebase="http://activex.microsoft.com/activex/ controls/mplayer/en/nsmp2inf.cab#Version=6,0,02,902" type="application/x-oleobject" height="525" standby="Loading Microsoft Windows Media Player components..." width="640" classid="CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95">
<embed name="MediaPlayer1" src="http://media.SITENAME.com/uploads/users/bobsmith/9 Yogananda PS.wmv" autostart="1" showcontrols="1" showstatusbar="0" windowlessvideo="false" width="500" height="375" type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaPlayer"  ></embed>
    </object>

 

The end result is that while the video plays fine in the editor window, it does not play when the html is rendered on the page.  I have tried complete reinstall, and also tried wmv files with no spaces...
