The movie problem is most likely a codec issue. Todd made this KFJ remake translation (and included quite a few great fixes by the way) and I think he used a different codec than the videos originally had. It's probably that the codec isn't compatible with your PC's setup. As an alternative, you can swap in the videos from the KFJ remake "project file" which comes with SoM. The project uses a separate translation (no fixes included) and it's videos use the original codec (I think).
As for the ingame black-weirdness, it's almost surely just that you need to change display devices to the "HAL TL" version of your video card. Have you tried changing devices since you got past the movie glitch?
