I have an old bugreport from february 2003 attached to this mail.

MPlayer interrupted by signal 4 in module: video_read_properties
- MPlayer crashed by 'Illegal Instruction'. It usually happens when you run it 

mplayer has crashed by any video-format mpeg,avi,....
no options are used ( -vo or -ao ).

The new bios enhance the athlon xp+ options.
I think mplayer use instructions of the Athlon XP+ that the bios has not 
aktivated. The k7s5a is a VERY cheap mainboard!
mplayer recognize an athlon xp+ use that instruction ( for better perfomance I 
think ) and..... crash!

With the inofficial bios these instructions are activated and mplayer can 
Thats my idea why mplayer plays with the new bios.

Here my old bugreport:
here is my BUG-Report:

since I have changed to a new mainboard (K7S5A) + ATHLON XP2200+ CPU I can't 
start mplayer anymore.
I have it compiled with mmx,3dnow,... without mmx,...
but nothing happened. I think it is a bug in your code. For more detailes 
please tell me, what can I do.

I have trouble with playing ANY video (avi,mpg,...)
mplayer was compiled on the same Computer were it run!

MPlayer interrupted by signal 4 in module: video_read_properties
- MPlayer crashed by 'Illegal Instruction'. It usually happens when you run it 
on different CPU than it was compiled/optimized for. Verify this!
- 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/bugreports.html section 5.b.
- 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/bugreports.html and follow instructions there. We 
can't and won't help unless you provide these informations when reporting a 
possible bug.
