Okay. That fits with what I thought I remembered - but in that case,
your statement above about "fringe codecs" is not yet accurate.

#define XACODEC_PATH "/usr/local/lib/codecs"
#define REALCODEC_PATH "/usr/local/lib/codecs"


Which is about what I'd expect to be there - but the first time I tried
recompiling (using my usual routine of "./custom_config ; make dep ;
make") after moving the contents of the codecs tarball into that
directory, the resulting MPlayer failed to play the file in exactly the
same way as my previous no-binary-codecs version had. After copying my
configure line out of 'custom_config', appending the appropriate
'--with-win32libdir' option, and repeating the 'make dep ; make', the
resulting MPlayer played the file just fine.

The possibility that it had just been a matter of some part of MPlayer
not getting recompiled had occurred to me (even though far more was
getting recompiled than seemed to be strictly necessary, given that no
part of the code had changed in the meantime), but if that were the case
then it seems to me that the same non-recompiling should have happened
the second time around.

Hmm... moving the /usr/local/lib/codecs directory out of the way and
reconfiguring finds a subset of the win32 codecs in /usr/lib/win32, even
though I didn't specify that directory. Perhaps this previous detection
(from before the current location was recommended) was persisting
through the initial recompile, even though the other directory had been
created by that point? It doesn't happen that way when I re-place the
directory and reconfigure now, but it's about the only explanation I can
think of.

In any case it doesn't appear to be a particular problem after all.

Will do.
