mplayer freezes X11 / machine unusable

[myemailu@…]

When playing this file:
​http://www.iam.unibe.ch/~ducasse/Videos/SeasideH-264Mov/001-GettingStarted2.mov

on my opensuse 10.3 system, mplayer opens the "video"-window und the "user-interface" window, then pints the "viedo"-output windo magenta and freezes the system. X11 does nor react at all, mouse cursor does not move, command keys (to kill X server or switch to a text console etc) do not work. The machine is basically unusable and needs a cold reboot.

When swiching off video output (-vo null), mplayer seems to work fine and outputs this:

If your machine or even just your X server hangs, that is _definitely_ a bug in your kernel or in some application running as root (e.g. the X server).
A normal program like MPlayer _may never_ cause such a thing.
Most likely it is a bug in the XVideo part of your video card driver, -vo x11 should help in this case.
I would assume it is related to the video having odd dimensions, in that case -vf crop=896:608 (with -vo xv) should help as well.
In both cases it would be a serious issue in you video card driver and you should report it to those developing that.
