Here are two methods (from this site), although neither are ideal:
Does not work for all videos!
Method 1: Go to http://www.youtube.com/html5 and request the HTML5 player.
Works for all videos but is a hassle.
Method 2: Copy the videoID and paste it after v= in the following link
http://www.youtube.com/watch_popup?v=&vq=large
Note: The videoID is the alphanumeric string after v= e.g., for youtube.com/watch?v=KxICWhyO7dI&feature=autoplay, it's KxICWhyO7dI.
