It started out downloading Sintel animated movie which was made using Blender. At first I use Totem movie player but it show some lag in certain scene. Try Gnome player, totally lag, try some setting but still not ideal. Lastly, VLC player, did some setting and everything works fine. Now I have 3 media player. All media player are not made the same. So I had to choose what works best. What else is there?
