'''Summary of the bug:'''
FFmpeg detect wrong duration of the vob files containing two titles. I'm
not sure about that, but from my observations and comparing how this file
is playback with MPC MPEG Splitter. I can say that real file duration is
21:34 and after 16:17 is video for other dvd title. Reproduced with
multiple files. Sample:
[https://dl.dropboxusercontent.com/s/asozlz6htli31ox/VTS_01_4.VOB?dl=1
VTS_01_4.VOB] Sorry for the size. Dropbox has bandwidth limit 20 GB per
day. I hope that will be enough.

'''What I expect to see:'''
Correct duration and ability to jump through whole file. Currently we can
do it only on the first part of the file (0-977s)
{{{
ffplay -ss 970 VTS_01_4.VOB
}}}
will work, but anything beyond 977 will start "second part" (sorry I don't
know how to call that) of the file from beginning meaning 977s.
{{{
ffplay -ss 1000 VTS_01_4.VOB
}}}
