I downloaded PowerDVD 8 from CyberLink at C/Net.  
Got the Free trial version.
Works like a charm.  Solved alotta MSMediaPlayer issues.
DVDs now play.
Mac
But I am NOT taking away from Skuzzys sails.  I just D/L'd a Beta Version that is ONLY free for a Month.
Cyberlink makes a trial version available for downloading.  And yes, once it is installed the MPEG-2 codec is installed which allows any video player to play DVD's after that.
