If you Youtube alot then you might find this handy.
A little while back youtube added the option to watch newly uploaded videos in HQ (ie original quality), but this option is not available on videos uploaded prior to this.
By adding &fmt=18 after the video ID, it will give you the HQ video. This works on all videos, new and old.
Make sure you add it after the ID;
http://www.youtube.com/watch?v=MCYLSGoTUyQ&fmt=18
If the url has something else after the ID it will be prefixed with the &. Remove it and replace it with the &fmt=18.
This is very handy for improving sound quality also.
