Fix Youtube's "We're sorry, this video is no longer available" problem

Are you having problems playing a Youtube video and it displays "We're sorry, this video is no longer available" like the picture below:
There are two solutions to fix this problem, first is to refresh your browser (hold shift + click refresh button for a full website reload). Continue refreshing until the video starts playing.

If the first solution is taking too long to work, the second solution is to play the Youtube video in high quality mode. You can do this by adding any one of these codes below to the end of the Youtube video URL in your address bar:

1) &fmt=6
2) &fmt=18
3) &fmt=16

An example of this would be http://www.youtube.com/watch?v=sXGBIPraQ40&fmt=18 where &fmt=18 was added to the end of the URL and the video is played in high quality. Enjoy!
