Youtube XL - Whiteboard Friendly Youtube

I have already mentioned the benefits of unblocking youtube at schools if it is possible, but another the problem is that when you load it up on your Interactive Whiteboard it's full of advertising, cluttered and needs a bit of attention to get full screen footage in HD that you can watch with ease on a large screen. 

Well the good folks at youtube have released youtube XL which is specifically designed to be viewed on a large screen such as a projector or media center PC offerering HD quality as the default setting and no advertising or comments which means the screen can be mainly made up of the actual video itself.  Access it here.
