]Ok, I've attached a patch that makes it an assertion, since that is what we 
]assume is the case from a libavformat viewpoint, right?
Ok, seems reasonable.

]I've made a simple fix for a problem with selecting a new audio stream if the 
]current dissapears. This rescanning could be made much smarter if we could 
]assume that all current streams will have the same id after rescanning.
Unfortunately we can't make that assumption with HDTV, but moving the 
audio scanning is a good idea.

]I'll see if it's a simple fix to make it possible to only have audio or video 
]next.
great
