For some reason "Windows Media Player" has stop playing sound. And I keep getting a message box popping up saying this. Link The thing is I get this message with all Windows Media movies, even the Windows Media test movie. I have a filling it is a codec problem, but I cannot find where windows codec are put, and I have looked. I know I could just use VLC or MPlayer but even they do not play all windows media movies. Anyone have any idea as to why this is happening.?
