My best guess is...For AVI, you still need to understand at least the 
packet/byte boundary of the underlay packet. You don't want to split a 
data packet across two AVI packet.
Also I believe it still need re-interleave the audio and video, without 
understanding of the codec format, it's hard to decide the correct way 
to interleave the things.
