Hello,
Sorry to hear you are having issues.
But I just tested it it I'm running Win 10 1909
Tried 2 DVD's one that I made and one that was Store bought .
and it played a DVD just fine using a couple different
Media Players //
Try Windows Media Classic player works fine.
If not you might need some Codecs to be installed
I use K Light Mega pk .
