There are two solutions for this problem. In both cases you have to find a computer in the actual country where the content is not blocked:
VPN services like Hola, which is also embeddable in a browser too, do exactly that: you connect to a server, which then lets you use a network in th preferred region
If there is no (free) VPN service, then you might use Tor: https://www.torproject.org/ which uses an network of nodes from around the world to forward your requests and your answers t a given destination. You also can choose an exit-node to be in a given country. So basically that node watches the video for you, and forwards you the content immediately. As a side effect, Tor also hides your identity.
