The trick is to visit the site hidemyass.com. This site is free to use and instead of using your own IP address, you will use this site's IP address.
Now, type htp://www.youtube.com as seen on the photo and click the Hide My Ass! button. YouTube will be loaded on the same page of hidemyass.com. Now search a video and enjoy those blocked videos. If searching displays an error, search from the regular YouTube site and just get the whole URL then paste in the Hide My Ass page. That will do the trick.
For those who are curious, some videos are blocked because of copyright issues or the owner of the videos only restrict viewing for their own country. What can we do right, they own these videos.
