Untangled the audio and video track from each other, and the parsing of the stream from the decoding of its data. Also fixed a memory leak as it turns out deleting a Surface doesn't free its data. You have to call free() in it. I have only checked the intro, not every cutscene, but that seems to work fine at least.
