get rid of centered play button from youtube video

I'm using the google youtube chromless api to create custom play controls for yotube vids on my site. Using the chromless player doesn't seem to get rid of the play icon that sits over the video at the start. I cant hide all the other controls using this:

 swfobject.embedSWF("http://www.youtube.com/apiplayer?&enablejsapi=1&playerapiid=player1", Id, "545", "300", "8", null, null, params, atts);

Googled this to death but can't find the answer.

Any ideas?
