I found this on Google, don't know if it will work
YouTube uses your computer IP address to determine your physical location / country. In order to bypass these country-specific restrictions on YouTube, try this trick:
If the URL of the YouTube video is http://www.youtube.com/watch?v=yEwD36Dk1jw – just replace the /watch?v= part with /v so your new URL becomes http://www.youtube.com/v/yEwD36Dk1jw.
