Some videos use non-standard proprietary codecs that no player will play properly. For example, Blizzard Entertainment's video files use a special codec, but they are at heart just MPG or AVI, I can't remember which. Also, floating around on the internet is that proprietary codec. Without it, some players play these videos upside down, some reversed, some just won't play them at all. Even the almighty VLC can't play them properly without the proprietary codec.
This wouldn't somehow be the case here would it? Any idea of the origins of this one file?
