I thought the reason FFMPEG 6.0 couldn't be ported to DOS is that it requires pthreads and that this was previously "impossible" in DOS. There is no pthreads binary in DOS. Your idea of offloading the actual h.264 decoding onto a second core and doing the video stuff on the first core should speed up DUGL player a lot.
