I even tried to replace binkw32.dll which was the obvious cause for the crashes, but the game didn't start at all after that.
However, I discovered that the game won't crash if the CPU usage is at least 5 % during video playback. I loaded a 10 hour Youtube video, muted it and started the game. The game FMV I tested was (warning:possible spoiler) Roper's Demise and Liftoff. Amazingly, the video plays and ends just fine if the CPU usage is over 5 %. If I exit Firefox, it crashes. Also it crashes if it's under 5 %: I tested VLC mp3 playback with 3 % CPU usage and it crashed as usual.
I hope this helps someone. I discovered this trick too late and the crashing really ruined the game for me :(.
