This is really a continuation of bug report #1538399.
I can't seem to attach a file to an existing bug. Here
is the attachment for that bug.

There is no tracking bug for mplayer (I don't think they use
a bug tracker). I have submitted a bug to the devel mailing
list, but the email was ignored. So I would guess that no
one at the mplayer project is interested in fixing it.
I'm going to close this since it is a config issue.
