4K movies don't work for the 'Movies & TV' app

[SirGalahad92]

Looks like it works for WMP like its supposed to, but WMP is basically the depreciated version of 'Movies & TV.'
I get the error code 0xc00d5212 and then it asks to purchase the HVEC codecs from the microsoft store.
I'm sure there's just one more step needed to get this working for it. Any ideas?

WMP and the Movies & TV App are 100% different softwares and share exactly zero code between them.
My codec software supports WMP because it uses Directshow codecs but the Movies & TV App uses Media Foundation Codecs which are distributed below.


For the Movies & TV App use the FREE video codecs below. (Some updates posted March 1st, 2021)

Media Foundation MPEG2

Media Foundation HEVC

Media Foundation AV1

Media Foundation VP9


If the Movies & TV App continues to fail, and as long as my codecs are installed, Windows Media Player will play everything you have.
Be sure to use the checkbox [x] WMP suggested settings
