If you look where the patch applies some changes to the Makefile it checks
to see if its being compiled under Darwin (codename for MacOSX).  If it is,
then the libavcodec is reverted to its last known good...otherwise it will
compile with the SSE code.

Attached is an updated version of the patch, it should be a little cleaner.
I've tested it several times and it works fine.
