Thanks.  I didn't know this.

I didn't mean to suggest that my processor does not have an MMX set.
I'm pretty sure I do have the needed support, based on the
output of ./configure.  Also, it _should_ compile.
So either I'm doing something wrong, the compiler is buggy, or the
code is buggy.  I'd like to find out which.

Also, I can't afford to spend CPU cycles when I don't need to.  I'm
not interested in watching movies, per se.  I'm setting up an
experimental research machine on which we will encode and run
algorithmic motion studies on test video sequences.  Lots and lots of
processing is (hopefully) going to be occurring while MPlayer is
playing.  I need all the cycles I can get.

Besides (again) I'm interested at this point in finding the problem.
Any help is appreciated.
