Sorry, I don't remember.  It was either an error message, or I got
noisy junk being rendered at the top of the screen.  It was not a
crash (not much help, I know).

In the mean time I was able to install (not build) the 32-bit pre-built
mplayer.rpm from fedora (actually "livna")  and it works properly
with -vo x11.  -vo gl2 also worked but the rendering was much slower
than -vo x11.

I would really like to rebuild the package from the .src.rpm for
32-bits on the target machine but I can't figure out how to do it.
The package detects that its x86_64 and compiles the 64-bit version.

Agreed.  I am using the same fglrx driver and things work with 32-bit
mplayer.

: 
: AMD64, EM64T, x86_64 (anything x86 running in 64 bit mode) is all the same
: at least for userspace. I personally decided not to care for some intel
: developer's ego and just stick with the original AMD64 name.

Clearly it's not the card in this case.

Ok, I'm glad of this.  Did you simply run mplayer on a 64-bit machine
and force -vc rawbgr24flip  ?

You might also be able to reproduce the error I got when using -vo gl.

: brrr. multilib is ugly. If you're lucky and it's something simple it will

I hope so.  FYI (you'll be happy to know :-), we just bought an Nvidia
Quadro FX5500 for this machine to replace the ATI card since I can't
get the ATI card to drive the 4096x2160 display under Linux.

Thanks for all your help, Reimar.
