In this case, it is specific to MOV and MP4, since it's caused by the
way we apply edit lists at the packet level (reordering, marking them
as discard, changing timestamps, etc.). Previously we didn't much
care to set the discard-flagged packet timestamps properly, which is
what this fixes. It's not a high-level vsync sort of thing.
