However, you still can't "just" decode the audio streams. You have to render the video portion first and then demux it. That's why it suddenly takes a million years to do if you try to demux an entire quarter of the movie. Even if it does it MPEG2 block by block, the work and the video streams have to go somewhere, and it can take a long time.
