I just tested it with Xenosaga. It only finds 8 of the movies! I know that there are definitely well over 50 FMVs in the game, so something is up. You wouldn't be willing to post the source, would you? I'm kinda interested in how you're doing it. Also, it seems only one of the extracted movies actually works. Okay, I'm off to try more games.
