This may sound stupid but I looked online for some time and I could not find how to make a YouTube player chromeless. I am making a web app and I am using the YouTube JavaSc
Alright, so I figured it out. So, if you are using JavaScript as I did (I believe it also works for AS3), simply, instead of writig the video ID in the URL (the one that you give to the embedswf() function), write "apiplayer". Then, after the video player has loaded, simply call the function cueVideo() on it (passing it the video ID of the video you want to show). This will make the video player chromeless.
