Movies sometimes don't play (no video, audio only)

[sanitystream]

I just got to the part where I asked the old lady (Keira) what her story is and the game then loaded a movie of some sort to show her history.

 

Problem is, I can't SEE anything, I just hear the audio.

 

Also, when the game first loads, I never do see the logos or anything, yet I can hear them. No video though.

 

Yet some other movies throughout the game DO play fine. This makes no sense.

 

Anyone else having the same problem? I'm playing on a Radeon 9800 Pro.
