Christoph Oelckers d98a567597 - halt the game timer when setting up a cutscene and when starting movie playback.
These are both lengthy operations that can take several 100s of milliseconds, so when starting a streaming video they can throw off the timing quite significantly.
With this the intermissiondelay counter could be removed as it was only there to flush the accumulated time before starting video playback.
