Things you will need:
- Firefox
- FoxyProxy addon
- Tamperdata addon
- Proxifier
- Socks5 proxy located in the US (any proxy in the US is ok)
Bypass first check:
First add your proxy to the Foxyproxy proxies and “http://releasegeo.hulu.com/geoCheck” to the whitelist.
Now make sure to use the “Use proxies on their pre-defined patterns and priorities”-mode. (Right click on the bottom right where is says “FoxyProxy:”) This will bypass the first check.
This check is actually client-side. It is not essential for playing the video. The player just opens http://releasegeo.hulu.com/geoCheck and checks if the response is either “valid” or “not-valid”.
Second check
The streaming servers are not checking your location any more. The proxy-server can be slow as hell but you will get a perfect image since you are directly connected to the streaming server. 
If you got everything right, you will now be able to watch your favourite shows and movies anywhere you want!
