To get this setup, create a simple.xml file within the config directory.

<params>
  <flashvars>
    <file>http://progressive.totaleclips.com.edgesuite.net/105/e105598_257.mp4</file>
    <image>http://www.movieposter.com/posters/archive/main/143/MPW-71686</image>
  </flashvars>
</params>

Then, you can use this code to produce the following...

<object id="dashplayer" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="100%" height="500px" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab">
   <param name="movie" value="/assets/dashplayer/dashPlayer.swf" />
   <param name="FlashVars" value="config=simple" />
   <param name="quality" value="high" />
   <param name="wmode" value="transparent" />
   <param name="allowfullscreen" value="true" />
   <param name="allowScriptAccess" value="always" />
   <embed name="dashplayer" swliveconnect="true" allowScriptAccess="always" src="/assets/dashplayer/dashPlayer.swf"
      width="100%"
      height="500px"
      border="0"
      type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"
      wmode="transparent" allowfullscreen="true" quality="high" flashvars="config=simple" />
</object>
