Modifying EmbedMovies plugin

Hello, I am trying to modify fckEmbedMovies plugin to work with yourtube/google videos.

I need just change url like this ->

http://youtube.com/watch?v=IkmpIXd9Q90

to html object like this ->

<object width="425" height="353"><param name="movie" value="http://www.youtube.com/v/IkmpIXd9Q90&rel=1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/IkmpIXd9Q90&rel=1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="353"></embed></object>

So, as I understood I need just to change "CreateEmbeddedMovie" function of EmbedMovies plugin to something like this ->

function CreateEmbeddedMovie(e, url) {

   var html;
   
   html = '<object width="170" height="140">';
   html+= '<param name="movie" value="' + url + '"></param>';
   html+= '<param name="wmode" value="transparent"></param>';
   html+= '<embed src="' + url + '&rel=1" type="application/x-shockwave-flash" wmode="transparent" width="170" height="140"></embed>';
   html+= '</object>';

   e.innerHTML = html;

}

Okay, it's done and works perfectly with text or images (<img> tag)...
But when I am trying to embed and object to my fckEdtor instance, I see nothing...Nothing happens and nothing in hmtl source...

Where I've made a mistake?

Thx.
