That is not entirely correct.
It is a know and a bit difficult to fix issue with formats like MKV.
But it should work for DVD and BluRay really.
Specifically, when an audio stream is found later on, MPlayer
should switch to it and start playing.
This is kind of required for streaming uses to work properly
with these formats.
Thus a sample with -dumpstream of the first few seconds would be
a good idea indeed, assuming it's not just happening due to using
an old MPlayer version.
