How to force TinyMCE to use flash youtube embed instead of iframe?
===

I am using TinyMCE 3.4.9 and am trying to force the media plugin to always use the Flash embedding instead of iFrame embedding.

For security reasons, I don't want to allow any embedding of iFrames.

I have formatted the URL manually to get a Flash embed object instead of the iFrame object.

IE- 

 - Flash embed: http://www.youtube.com/v/fWNaR-rxAic 
 - iFrame embed:
   http://www.youtube.com/watch?v=fWNaR-rxAic

Is there a way to do one of the two:

1.  Onchange of the embed file/URL field, modify the URL so that the Flash object will be embedded by default. (http://www.youtube.com/watch?v=fWNaR-rxAic would be converted to http://www.youtube.com/v/fWNaR-rxAic)
2. Change the call to youtube so that youtube will return the Flash object instead of the iFrame.

My TinyMCE initialization code is:

    <script language="javascript" type="text/javascript">
    	tinyMCE.init(
    		{
    			paste_remove_styles : true,
    			gecko_spellcheck : true,
    			theme_advanced_font_sizes : "1,2,3,4,5",
    			extended_valid_elements:"script[charset|defer|language|src|type]",
    			theme : "advanced",
    			mode: "exact",
    			plugins: "inlinepopups,emotions,searchreplace,paste,media",
    			elements : "blogcontent",
    			theme_advanced_toolbar_location : "top",
    			theme_advanced_toolbar_align : "left",
    			theme_advanced_buttons1 : "bold,italic,underline,strikethrough,sub,sup,|,fontselect,fontsizeselect,forecolor,|,link,unlink,|,backcolor",
    			theme_advanced_buttons2 : "justifyleft,justifycenter,justifyright,|,search,replace,|,image,charmap,emotions, media,|,undo,redo",
    			theme_advanced_buttons3 : "",
    			theme_advanced_resize_horizontal : false,
    			theme_advanced_resizing : false,
    			file_browser_callback : 'file_browser',
    			relative_urls : false,
    			remove_script_host : false,
    			paste_retain_style_properties : "font-size,color,font-family,background-color",
    			setup : 
    				function(ed)
    				{
    					ed.onKeyUp.add(
    						function(ed, e)
    						{
    							ed.nodeChanged();
    						}
    					);
    				}
    		}
    	);
    
    </script>
    	

Thanks,
