The machine is clean emerge -DuN world, revdep-rebuild. As a test I just rebuilt libXv and libXvMC but it still crashes. dragonfly ~ # emerge -pv1 libXv libXvMC These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] x11-libs/libXv-1.0.4 USE="-debug" 0 kB [ebuild R ] x11-libs/libXvMC-1.0.4 USE="-debug" 0 kB Total: 2 packages (2 reinstalls), Size of downloads: 0 kB dragonfly ~ # Other mplayer formats do not crash. I've tried x11, gl & gl2. They all work fine. Only mplayer File.avi or mplayer -vo xv FILE.avi crash X so it seems to be an xv thing. This all used to work before the upgrade. I'm going to move on to Paul's suggestion about using an xorg.conf file and see if that helps. - Mark
