@ Esoteric_Monk: I was referring to the OP. However, I can say with some certainty that if you are having an issue with movies with your setup, it is due to the Hack.
ZimmMaster has a helpful thread in this subforum for issues with the Widescreen hack.
Out of curiosity, what native screen resolution do you have, E_M? Would you not be better off using a native resolution from the stock game? Use one that matches the ratio that you have. I honestly have never understood the benefit to using a patched .exe - they always seem to cause more problems than they solve
