My streaming stuff: what will I still be able to see?

I understand that UK/US Netflix are different. However, my primary concern is the dozens of movies that I *own* exclusively on a streaming service. (My kids scratched so many discs that I gave up on them and just buy streaming versions.)  But... now that I'm moving, are all the movies I own on Amazon, Xbox, and VUDU going to be inaccessible? VUDU states that they don't work. We streamed our owned Amazon content from Canada, so I'm hopeful there. Xbox's answer is ... mixed https://answers.microsoft.com/en-us/musicandvideo/forum/xboxvideo/xbox-video-region-lock-question/39a36499-fc0e-4e51-bad3-95633fd0d219.

The VUDU thing is annoying, since it's owned by WalMart, which owns ASDA... seems like it could be an easy business deal.

The reason is that there's complicated licence deals for music and movies that are very specific to particular countries.  Trying to make an app that could allow you to play a movie in one country that you bought in another would be pretty difficult for the small number of people who have that problem. 

I think your answers are either a VPN to pretend you are in America, or just buy used dvds of those movies you care about on Ebay.

If Amazon cared about customer service, it would offer the option of free DVD backup to customers who bought the online version and then were able to provide evidence of a move to a new region.  They probably already have the DVD inventory, so it would be easy enough to accomplish.  And, I mean, you bought the content.  If you'd bought it as a DVD originally, you could've taken it with you.  Why not give the option now?

I don't think Amazon will be a problem. RE the xbox, are you taking the xbox with you or are you going to be getting a new xbox and using the account on that?
