Thank you for your response. 
 
pasting <param> would not work locally - however did work on the demo page. 

The below additional example will not work locally as well as on the demo page

1.  Copy the following into the html tab of the editor:
        <object>
        <param name="AudioStream" value="-1">
        <param name="AutoSize" value="-1">
        <embed type="application/x-mplayer2" pluginspage = "http://www.microsoft.com/Windows/Downloads/Contents/Products/MediaPlayer/"
        displaysize="0"
        showcontrols="0"
        autostart="1">
        </embed>
        </object>"
2. Click the Normal tab
3. Click back to the HTML tab and notice the param tags are missing
