Keep in mind that I am referring to this:

yes, I am saying that the original code has already gone through a complete optimization process, everything is written in written in assembly, and you are at 970us on your 1ms time budget. (I'm not pulling those out of thin air, I was literally at a client yesterday with some real-time code with a 1ms deadline on a desktop OS and we have to cram as much things as possible in that millisecond)

Well in that case there is no way around upgrading the hardware, a 486 won't play a MP4 no matter how hand tuned the Assembly code is.
