I already try unblock-us and unotelly, both works fine, but unotelly had more supported US channels also the support is very fast (1hr response), a lot of custom device modifications to work with apps like in US for SmartTVs; additionally they had more DNS servers around the world and several options to automatically update your IP.
I have been using UNO Telly, awesome experience. Try out their 8 day gold trial and you will be amazed. Netflix, Hulu plus and lot more you can access even outside US.
