One possible way to get around the error is to use a VPN. If you use a VPN, there is no longer a direct connection to the website server. Your pc first connects to a VPN server. This server forward all data to the website server. The website operator therefore only sees the IP address of the VPN server. So you have to connect to a VPN server in the country where you want to watch your video and then you solved the problem.

A very good solution for the problems of that kind. I am also using this way, VPN connection, to get access to some internet resources that are not available because of your location. For example there are some learning materials such as videos of lecture that you may watch only in the university local network. To do that from outside you may use your university VPN access point
