AVI container doesnt have an Aspect Ratio ( AR ) flag unfortunately, so you
would have to reencode your movie to change it.
In the future you will be able to mux your existing video and audio streams
into an MCF container and change Aspect Ratio for playback by simply editing
the AR flag in MCF header.
