Comment (by navilor):
This is the command line I just ran to replicate the problem.

I have just uploaded a zip file called Ticket 7055-001.zip that contains
all of the following:
1) S01E01-small.vob which is the source file.
2) S01E01-decimate.mp4 which is the output file.
3) The console out log file called 7055.log.
4) The ffmpeg2pass-0.log file.
5) The ffmpeg2pass-0.log.mbtree file.
