[MPlayer-users] "DMO video codecs" multifile crash, 100% reproducible

I have a whole bunch of .wmv files that I have been trying to play
with mplayer (1.0pre6a on Red Hat Linux release 8.0). All of them
use the dmo codec ("Opening video decoder: [dmo] DMO video codecs").
Apparently mplayer is not resetting something correctly when using
this codec because it always crashes at the start of the eigth file.
I can run mplayer with the one file eight times on the command line
and have it crash when it reaches the eigth instance of that file.
The backtrace looks useless to me, apparently it dies in one of
the dlls. Anyway, here's what I've got:
