I don't bother with pcsxbox anymore, but when I first tried it that was the only game I was interested in. I had the exact same problem, and I was using bin/cue. You'll know the problem isn't your cd image if you play it in epsxe on your PC. It'll work fine there. The problem is either the version of pcsxbox, try a newer one if there is one, or it's the settings. Or, pcsxbox just can't play SOTN's fmvs with sound for some reason.
