Hello everyone,

I recorded tv with mencoder:

mencoder -endpos 60 -tv driver=v4l:norm=PAL:width=640:height=480 -oac copy 
-ovc lavc -lavcopts vcodec=mpeg2video -vop crop=624:464:8:8,pp=lb -o 
test.mpeg tv://

unfortunately mplayer crashes after displaying frame no. 1

mplayer -v -ao sdl -vo x11 test.mpeg

I uploaded a sample file that will crash PRE2. It's name is 
"This_File_crashes_PRE2.mpeg"

Thanx for the great player,
Jörg

MPlayer interrupted by signal 11 in module: decode_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. For details, see DOCS/en/bugreports.html#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/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible 
bug.
