it won't work.
at least vob and mpeg is the same file format. i've seen mpeg2 files (aka
vob) having mpeg audio sterams (counted from 0) and ac3 sterams (counted
from 128). so, how to select between them?

i won't change this.
mplayer prints (at elast with -v) the ID of streams found, user shoudl try

maybe, for real dvd, i'll add support for specify aud by language id, like
-alang hu, as .ifo file contains the mapping from language to aid.
btw a few dvd has multiple audio sterams for the same language, one with
film makers' comments etc. how to select those?

run mplayer with -v

==> Found video stream: 0
==> Found audio stream: 128
==> Found audio stream: 129
