Since I reinstalled Windows 7 two weeks ago, my PC has been playing up and acting a little strange, maybe the installation of Windows wasn't right or something, I don't know, but Windows Media Player 12 is now refusing to play MOV and MP4 videos. If I play an MP4 video rendered in AVCHD I can only hear the audio, I don't see a picture, and if I play a MOV file I have the same problem. These videos worked fine before I reinstalled Windows, so I know WMP12 can play them. What's up? I don't want to use VLC or any alternative media player as I like WMP12.
