Thanks a lot for your fast and effective reply about the 
--enable-runtime-cpudetection option!!!

But I'm a little confused: I tried compiling with your option 
and of course it works, so that, as far as I understand, mplayer 
automatically chooses which optimizing CPU flags to use depending 
on the CPU is running on.

So why do you say that it is not possible to make a binary which 
runs optimal on all them?
The one I just built with the option you told me [and all cpu 
flags on] seems exactly that.
Where am I wrong?
