I was trying to play the videos in the "Cinematics" folder of World of Warcraft - Cataclysm
but they have a FourCC of PMVX which nothing can play.

They have a standard AVI header but I can't seem to trick them into playing by editing the FourCC.

Hmm, interesting... here's a different video, notice how the first says "vids digm" and this
one says "vids divx" yet they both say PMVX and that is what GSpot says the FourCC is.

Also, I've heard that PMVX is "Predictive Motion Vector for H.264" but that doesn't mean much to me.
