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
renderers.
It is still possible, however seeking sometimes produces incompatible
files.
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
output.mpeg
Confirmed with 63951ae (latest)
Here are two files, 7MB each, that show the bug. One was made by f1fdd20
and the other 967facb:

http://www.spirton.com/uploads/FFmpeg/ps3compat-f1fdd20-withoutbug.mpeg
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.
