--- Comment #2 from david.dljunk@gmail.com --- Based on the observations that: 1) the Intro to Independence War: Defiance plays fine in the Mac driver and 2) the X11 driver plays both Intro videos fine and 3) that I get audio but no visuals; I think that the problem stems from the fact that the mac driver is not loading the appropriate codec for the Intro executable for the vanilla game - and more more precisely is maybe only not loading the codec when playing the video is the first thing that happens in the executable (because that's a major difference between Defiance and the base game - the Intro in vanilla simply starts while the intro in Defiance takes place after some the corporate logos play). Another possibility is that the two Intros are encoded differently and the Mac driver is able to play one with the supplied codec and not the other - however, it is odd then that the X11 driver can play the video.
