If you do not pay MS, you can't stream Netflix on an xbox.
I was given an xbox, by someone who upgraded to a newer model. I intended to use it as only a netflix player in one room but it turns out that it doubles the monthly cost of my Netflix subscription because of the "gold fee". Its the only netflix streaming device I know of that adds an extra fee. I guess if you are using the xbox gold for other services, the the cost for streaming netflix to the xbox is just a fraction of the gold fee then. But still that's ridiculous and certainly not my case.
My God, the price of Xbox gold was exactly the same before offering Netflix, MS doesn't takes a cut from Netflix.
If one wants to understand it's not difficult.
