In preparation for the roll out of the Spring dash update, Microsoft brought down the hammer (of dawn) on country specific online content. More specifically, they are limiting access
to faked US accounts. Right now, US Xbox Live members have the largest supply of video marketplace content which has caused an underground gamertag market. Live members from other countries have been creating new gamertags, specifying a US residence and getting access to the huge supply of exclusive US content. But that is no more, because Microsoft has implemented a new system that knows which country you are from no matter what you tell it. And before you get on Microsoft's case you may want to direct your anger towards individual governments or the movie studios in general. Microsoft is just playing by the rules guys.
