My guess with that Bravewords one is that it was embedded into the page incorrectly, possibly using YT code instead of FB video code or something. But usually if it's "not available in your area" it's regional thing based on the IP address. I know CBS and the American ABC do it to protect copyright, not sure why but we often can't watch clips from Jimmy Kimmel and the like here for a day or so. (Not that I want to often)
