O.T here to the original question - but IMHO what's the point of using Any Microsoft media player when the Free VLC player will play almost every known audio and video codec on the planet.
It can also play DVD Isos (if commercial ones then rip to iso removing encryption - AnyDVD (now finished but you can still find it on various Internet archives archives -- old DVD's work just fine with it) which has built in libdvdcss and regional bypass is a good tool there, and VLC can also act as video server and media format converter too. !! - A bit more complex but fine. VLC also has lots of audio and video settings too for best picture / audio playback.
