I have exactly the same problem, nothing shows (no intro, no logo, none of the cutscenes/comic-book-like scenes as found in the game's folder). Well, the scenes rendered with the game engine work though.
I'm wondering if it's not because of nVidia Optimus, it's rare but some games really don't like it. I've checked which GPU the game is running on, and it keeps "locking" on Intel HD, even when nVidia GPU should be used instead. Anyway, whatever the graphic card it may be relying on, no cinematics at all. I've tried with "disable desktop themes", adding the game as an exception in k-lite codec pack, lowering sound frenquency... nothing.
I've found with other games that running in a window often helps, maybe it's possible with this game?
i have the same problem, no movie is showing.
Also a Laptop with Optimus, maybe you are right and this is the cause...i tried alot to get it orking but no success so far. If you find a solution please be so kind to post here, thanks
