Well this is simple
Find a video you want to watch, whatever it is, then at the end of the link tag add in &fmt=18
just copy and past that to the end of the video link (no spaces) and the video will go into higher quality
Upside: Better quality, easier to see stuff and just better
Downside: longer loading time, and more laggy videos, Unless you have an amazing computer smile.gif
Hope this helps some of you with youtubes crappy quality
and again u add (&fmt=18 ) to the end of the tag! Enjoy

Cool feature. =)
