Hi T.P.E
Greetings! I am Vijay, an Independent Advisor. You should download and install MPEG-2 Video Extension from Microsoft Store.

If WMP doesn't play MPEG2 even after that, you can use Films & TV app supplied with Windows 10.
Alternatively, you can use VLC media player as well - To download VLC - https://www.videolan.org/vlc/download-windows.html
