Playing downloaded Movies and TV on Xbox one X

Hello,

Xbox One does not support 4K movies or games.

Xbox One S, supports 4K movies.

Xbox One X
supports 4K games and movies.

If you have 4K TV I recommend Xbox One X. If you have only Full HD TV, so Xbox One X can switch to Full HD mode. All the more power it can put into games.

There are over 130 games that are for the Xbox One X.

If you want to see a 4K Movies (streaming/disc) you will need to have a 4K TV. (With Xbox One S and X)

Also if you want to play a game on 4K the game need to be 4K compatible and a 4K TV (only with Xbox One X)

Regards!

I'm having the exact same issue on the Xbox One X but with the Movies and TV app

Correct, and just to add a reference point,
this is covered on this page, here. It specifically says:

• Purchases from Movies & TV are not downloaded to your console but are streamed over the Internet to your console or other Movies & TV-compatible devices. For more information, see Microsoft
  Store: Movies & TV.

Now, what you CAN do with that, is sign up for
Movies Anywhere. Then all of your eligible Microsoft Movies & TV content will sync over with Movies Anywhere and then you could use a service that DOES allow you to download and watch the movie offline, though through a very cursory search does not look
like there is an option on Xbox One? Vudu is a Movies Anywhere app, though I have never used it to see if you can download titles for offline play.

Thanks for adding the extra info.

I would point out though that Movies Anywhere is only available in the US.
