Have you ever experienced “This video is not available in your country” on accessing YouTube?
you can easily bypass these YouTube Restrictions

However, YouTube can be easily tricked into displaying the videos in all countries by altering the URL a bit, for example instead of the regular url – http://www.youtube.com/watch?v=UNIQUEVIDEOID, access http://www.youtube.com/v/UNIQUEVIDEOID (here UNIQUEVIDEOID is a unique 11 character video id code of the particular video).

Example:
Try watching this US specific video using the regular URL – http://www.youtube.com/watch?v=I9ciR9qR1dU, now try this altered URL – http://www.youtube.com/v/I9ciR9qR1dU.
