Go to the video you want to view.
The site will display that the video cannot be played in your country.
See in the address bar and you need to manipulate it a little bit.
Your URL will be like http://www.youtube.com/watch?v=QJO3ROT-A4E&ob=av2e
You just have to remove “ watch?v=” and replace it with “v/”
Now your URL will look like this http://www.youtube.com/v/QJO3ROT-A4E&ob=av2e
Now run this URL and you will have access to the blocked video.
Note:This is a simple trick and it may not work always. Try your best!!!
