What difficulties did you have acquiring the app? For me, the process was such a non-event I don't even remember the details.
Edit: I Googled it
Was that it?
No, it was this (from bad memory);
- Insert a Blu-ray or DVD disc into your Xbox One.
- Select the Blu-ray Disc app when it appears.
- On the broken link you get taken too scratch head
- Repeat steps 1-3 because clearly you're doing something wrong
- When the same thing happens do some googling
- Test a DVD to at least ensure the drive is working
- Search for the UHD app thinking that the reason it's not playing the disk is because it's a UHD disk
- When no results are found try searching 4K
- When no results do some more googling
- Return to Xbox and try one last search, Bluray and select the app
- Blu-ray player app details page, select Free or Install.
- Wait for the download
- Your disc should start playing automatically.
