This demuxer take as input 3 demuxer, but one can be in two place. Like video and
subtitles, or audio and video. Even the 3 if you want :)
For speed dunno, _perhaps_ it can be better for badly interllaved files, but I doubt.
We should check. Anyway their is still the caching issue.I think to do it like this :
the cache option will be global to the 2-3 streams, but two option like audiocache 
and subcache can then be used to override the cache value for the audio and sub 
streams. This way we can select the exact wanted cache size for each stream, and
we keep a simple way for the common case (ie the same cache size for all streams).
