sword of the berserk problem

[itoledo]

hi. i've downloaded sotb a few times on the net. all of them (including the kalisto rip) have a very annoying problem: every poligonal creature on the game starts rotating when the game is playing some in-game video. it's really weird; i've burned 3 different downloaded rips and all have the same problem. using the "fix" found in megagames didn't work either.
any hints?
