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.

 

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'.
