So, as listed above, I'm having trouble with Dark Forces 2's cinematics. At least on level 1 anyway. However, I saved and reload the same point, and the problem still persists:

So, at the end of level 1, before the cutscene plays, the game suddenly minimizes to my desktop, only it's that sort of magnified version of your desktop you get when you play a game sometimes. Anyway, the problem is, even though the window is minimized, the audio (and presumably the rest of the scene) still play. So, I figure, "just click the program in the task bar and it will open back up." But when I click it, everything stops as if the game were paused/ minimized. And yet the game's first two cutscenes (the game's opening and the level 1 intro cutscene) played just fine.

This problem is only happening in Dark Forces 2. I haven't checked Mysteries of the Sith yet.
