I tried several services already. Most of them did not offer the required bandwidth for Hulu & Co. Then someone in our forum suggested BlackVPN. I gave it a try and was really impressed by the speed offered for this price.
Installation and connection via OpenVPN was very easy and straightforward. Almost all services were working with BlackVPN. Only Amazon "Video on Demand" does not allow to buy because of IP geographical restrictions.
Sometimes the bandwidth was not enough so stuttering of movies occured sometime. My guess is that this depends on how many users are using the service the same time.
But all in all I'm really happy with BlackVPN. And I will be keep using this service for sure.
