You can watch the video from here:
Unblock YouTube Videos - SSL Encrypted Video Proxy Make sure you select the London server, so that the request Youtube gets isn't from the US, and paste in the video URL:
https://www[ put the . here]youtube.com/watch?v=BK-_d1Bnuec
It certainly appears to be a video that you (your husband?) produced, so it is something you did. I don't know much about video editing and production, but being available through a proxy in England offers a clue. I think I know what the problem is, and it has nothing to do with South America. I suspect that the video does contain content from Columbia. Columbia Records. Youtube recognizes the music as Columbia's copyrighted property. The catch is that I've encountered plenty of videos where only the audio is disabled, which eliminates the copyright problem. I haven't watched the video yet. Will I find that you've included video that may be copyrighted by Columbia?
Either way, you probably need to remove part of the content if you want it to be easily available in the US.
