We still need to know the field dominance of the output device. If you can always guess correctly though you're fine. We'd also need to never miss a frame, again that's not too big a deal. We'd then need to sync audio to the vsync. Doable. But all of this depends on knowing the refresh rate and having timestamps. -- Billy Biggs vektor@xxxxxxxxxxxx
