I'm aware of the fix that was posted on getting jQuery dialog to appear in front of youtube videos, but I'm using their new IFrame embedding method:
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
How can I get the dialog on top of the video?
