I had a similar issue on my 64 bit win 7 system and how I fixed it had two parts because I got it through steam with the big SW package. Anyhow if you got it through steam make sure to turn off the steam community in game check box by right clicking the title in your library and selecting properties. The next step is to go to the folder for your game, in the case of steam wherever you download your steam games to ...steam/steamapps/common/swkotor, and run the swconfig application and when it comes up uncheck enable hardware mouse and check disable movies. It only turns off the startup movie and not the cutscenes so far. It worked like a charm for me so I hope it helps.
Well I run the steam version and used all the tricks listed here and on the steam boards, I do not know if I made a mistake somewhere along the lines, but I can't see any cutcenes, only the ones in engine are played not CGI's like whenSpoiler:
