I've read complaints that seeks wouldn't hit the target spot exactly, probably most of the times due to adjusting the seek to the next keyframe. When the players are seconds from each other, I would suggerst al little seek in one of them, but when they differ something like 0.2s, the speed_incr should work more smoothly, wouldn't it?
