Did you try with speedhacks or advance option? Sometimes those fix some problem. Perhaps that problem in your Plugins setting especialy with plugins cdvdrom. If that is movie or FMV and you can't fix it. You have to skip it manually with option enable patches after you got a code in skip MPEG (must enable it) from patch browser.
Iam not sure, i haven't try that game, i suggest you to make some experiment to those plugin and all of setting, which are the best for your system and perhaps you can OC your CPU more higher. Make sure in grapich plugin to check at native resolution because your Vgacard is kind of limited so uncheck wvsync option and play game with windows mode.
