Windows Media Player Troubles

So for some reason a long time ago WMP stopped showing the pictures of DVD movies. It plays the sound just fine but the picture won’t show up. I can even select buttons in the menus. So I said screw it and downloaded another movie player (PowerDVD) which works just fine. But know I’m curious as to why WMP is being so stupid. Anybody have an idea about what the problem could be? Thanks :flower:
