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: $ gdb mplayer GNU gdb Red Hat Linux (5.2.1-4) Copyright 2002 Free Software Foundation, Inc.
