So I just started up Fallout 3 and notice that the FMV is slow; some parts of the screen move faster than others (like I'll see the bulb in the top third and two other bits of video below it). I noticed that I can fix the problem by replacing the binkw32.dll file from a newer game (I used one from Mass Effect 2, where I know the FMVs run fine) which makes it run faster but it's still stuttering and occasionally the sound has to pause. I've actually tried playing the movie files through RAD Video Tools and they run just fine. I wonder if there's some fully up-to-date dll file I can get to get the FMVs running at proper speed.

For the record, my specs.

Intel i7-930, quad core
3.25GB available RAM
Radeon HD 5850
Realtek HD Integrated Sound Chip
Windows XP SP3 32-bit

Any help on this'd be great.
