GOM

GOM sounds like some sort of toy you wouldn’t think is was one of the most versatile media player I know of. GOM comes with a lot of audio and video codecs already installed and if it doesn’t  have the codec it will help you find them. GOM can even play flv files. And it does this all with very little resources and best of all it’s free. You can get it at   gomplayer.com . By the way it can play files vlc can’t.
