Watch YouTube Videos in Higher Quality

To watch YouTube videos in high quality, all you need to do is add the string "&fmt=18" to the end of the link.

So if you had this YouTube link, http://www.youtube.com/watch?v=eBGIQ7ZuuiU, you could watch it in high quality by viewing this link instead, http://www.youtube.com/watch?v=eBGIQ7ZuuiU&fmt=18.
