How to watch youtube videos in a better quality

Hello friends......I am going to show you how to view any Youtube videos in higher quality.All you have to do is
look up a video on Youtube and then in the URL address bar add this code onto the end.


"&fmt= 18"..(without quotes)
So, as for Example :
www.youtube.com/watch?v=OAXTCnux

would become

www.youtube.com/watch?v=OAXTCnux&fmt= 18

Now load both these videos and check the difference in quality.
