whenever I have to recommend someone a movie (or music player) 1st rule is to use only 1 app 2nd rule is to use external codecs (shared by system with other apps, and not player alone) 3rd and final, player must not be garbage therefore for movies I highly recommend (k-lite codec pack, or any simmiliar that gives shared codecs) and media player classic home cinema (home cinema gives GPU acceleration for HD movies)
