 Summary of the bug:
 Prior to the commit https://github.com/FFmpeg/FFmpeg/commit/967facb it was
 possible to produce MPEG-2/AC3 files compatible with PS3 and other
 It is still possible, however seeking sometimes produces incompatible
 I have confirmed that it started with 967facb; f1fdd20 and releases prior
 to that work perfectly.

 How to reproduce:
 ffmpeg -ss 2 -i input.mkv -bufsize 7000000 -maxrate 54000000 -f vob

 Confirmed with 63951ae (latest)

 Here are two files, 7MB each, that show the bug. One was made by f1fdd20
 and the other 967facb:


 MediaInfo doesn't report any difference between the two files except the
 new one has a "Delay relative to video" of 26.5 hours, whereas the older
 one (which works) doesn't report a delay.
