Even if the keyboard does not react anymore?

valgrind 3.0.1 shows many errors, but doesn't change anything about the
freeze.

Thank you for testing! After a dozen power offs, I know now that the
necessary command to freeze my computer is:
mplayer ia2_tsr_land_r4c5a.mov -vo xv:port=124
I use port 124 to be able to use xv and xvmc at the same time - I never
found any information about what ports are in this context. What could be
wrong with using another port than 123?

Fortunately, I found another command that simply crashes mplayer:
mplayer ia2_tsr_land_r4c5a.mov -vf format=rgb32,scale

Thanks for looking, Carl Eugen

MPlayer interrupted by signal 11 in module: filter_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't
