Crash seems to be because BA.LVL isn't found.. behavior is just to blow up at the moment. You say the level browser opens? The textured quad rendering there is the same as what the FMV player does so if one works then they should both probably work.
x64 build isn't too well tested, I'll try the latest x64 build with AO and AE FMV's.
Edit: Seems to work, perhaps AMD issue as I think everyone who used it so far had NVIDIA cards.
Edit x2: Perhaps you could try a debug build - that has checking on every openGL call.
Created an issue for this here:
