Unfortunately for you, that _is_ the current state of affairs in
mplayer.  Please help fix it if it is important for you.  Arpi and the
others have different immediate goals.

I'm currently looking into replacing libac3 with the newer a52lib.
This will not be without cost until performance enhancements from
mplayer's libac3 branch is ported back into a52lib, but I think it
will be worthwhile for both projects.
