Windows 10: Movies & TV can't play .mp4 and other local files?

I just went to look at an .mp4 file, but it didn't open in Movies & TV, which I were using all the time before. So I tried to reinstall/install and repair even through Powershell and Revo Uninstaller which should be capable of removing all leftover files and registry entries Movies & TV, with no effect. I can't play any files and Movies & TV also isn't in the menu for "open with". When checking in the settings if I can set Movies & TV as the standard for .mp4, etc. files I realised that there it wasn't showing up either. Does anyone know how to help? Everything I found on Go

Movies and TV app - MP4 file problem

Hello all,
Running Ver 1607;
As a result of a seperate issue, I recently changed to 'Movies & TV' app as my default in lieu of Windows Media Player.

When I play MP4 movies on my PC, the video is jerky and the audio is out of synch? Basically they are not watchable. AVI files play ok.

If I play any MP4 from my media player (windows share), it plays normally.

If I play any MP4 using WMP it plays normally.

I have run Defender and Malwarebytes (free) just to be sure and they both come up clear of any nasties.

Have I somehow got a corrupt MP4 codec in 'Movies & TV'? Is this possible?

How would I rectify this? Prefer to stay with 'Movies & TV'.

 

Movies and TV app - MP4 file problem

Thanks to Ivan & Jimbo45 for some suggestions to use another media player.

Anybody else care to offer a suggestion on why Movies and TV app is not working for MP4?
Should I try to uninstall and then re install?

 

Movies & Tv app stopped playing my mp4 movies

When I try an play any Mp4 movie in the Movies & Tv app it attempts to play, gives the movie details like running time but will not play and closes the app. It was working fine. Restarted the computer several times.
