There is no legal means for someone to restrict where and when I can and cannot choose to view or use content I own, as much as they would love to think so. And they indeed love to think so: I've actually seen companies claim that it is illegal to use the software they sell outside of the country they sell it in.
If a movie by company X is released in country A but not country B, company X cannot prevent me from watching their movie in country B. I may have to go out of my way to import a copy, but there is nothing illegal about doing so (at least not under the laws of typical Western countries).
If this wasn't true, it would basically be illegal to take any sort of media-carrying device (laptop, iPod, etc) outside of the country where you bought the relevant media.
