When I insert the following code into a post and preview it, it looks fine. After I submit it, it turns to code with the player not fuctioning. I make the change from UBBcode to HTML. It seems that turning on HTML doesn't work for all html tags. Is that correct?
Code
<object id='mediaPlayer' width="320" height="240"
      classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95'
      codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701'
      standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'>
<param name='fileName' value="http://www.ariellemiller.com/HighwayToHell.wmv">
<PARAM NAME="AutoSize" VALUE="0">
<param name='animationatStart' value='true'>
<param name='transparentatStart' value='true'>
<param name='autoStart' value="true">
<param name='showControls' value="false">
<param name="ShowStatusBar" value="true">
<param name='loop' value="0">
<embed type='application/x-mplayer2'
            pluginspage='http://microsoft.com/windows/mediaplayer/en/download/'
            src="http://www.ariellemiller.com/HighwayToHell.wmv"			width="320"
            height="240"
            autostart="1"
            autosize='0'
            showcontrols="0"
            showtracker='0'
            showstatusbar='1'
            showdisplay='0'
            videoborder3d='0'
            loop="0"
        ></embed> 
</object> 


Is there a way around this?
