As far as I know that version of mplayer is bugged. I can't guarantee that
your problem is the same one I had, but if I am not mistaken the bug is
present in that release. Please, try 1.0_rc4_p20091026-r1 and see if the
bug goes away. I will open an STABLEREQ bug to speed up the stabilization
of this version, and the masking of older ones. After all, they should be
hard masked or at least patched to fix the bug.
