Change ".balign 16\n\t" to ASMALIGN(4) and "/nop" to " # nop". The new
version is what other code in MPlayer uses, and works with old
assembler versions like that used on OS X.

I don't know why Michael Niedermayer disabled it but:
my benchmarks of 25 frames for TIMER+SUBTITLE (measured by RDTSC):
Non-MMX stuff:
total=306142159
MMX stuff:
total=159534150

I've found that mplayer's measuring is not precise :(
Here my test with using RDTSC:
Old stuff:
rd_tsc: 774377
rd_tsc: 765985
rd_tsc: 265309
New CPU optimized stuff:
rd_tsc: 661154
rd_tsc: 641317
rd_tsc: 222448
New MMX2 optimized stuff:
rd_tsc: 269544
rd_tsc: 329189
rd_tsc: 173110

nick why did u remove the #if 0 around that code without testing it?

Special notes for Michael Niedermayer:
Are you still here?
If you don't like for(cond;cond;cond) C-constructions and prefer
asm ones: "jb 1b" then use .align 16 pseudo assembler instructions
else loops rather will be not aligned on correct boundary.
(16 it's for K7 for pent should be 8).
Your parts have a lot such lacks.
