Family Guy and The Dark Knight are coded as separate field pictures,
bottom field first. ffmpeg hands each pair back as one frame, and we
described it with the first field's SEI record only.
The UMD Video player (video_main_plugin.prx) shows such a picture a field
per vsync, and takes the field order from comparing the output times of
the picture's two records. With the second left empty it always chose
top first, so every pair ran backwards in time and the picture jittered
between frames. Now the pair carries both fields' timing, the top field's
record first.
