Some dvds have probably bugs which cause incorrect timestamps sequence. For
example 887266666 then 847266666.
It is not a problem if you play it. But it will cause problems if you convert
it to vp8/mkv.

This is probably reason for Bug 712219

sample file is here:

you can catch brocken timestamps with this command:
gst-launch-1.0 -vm filesrc location=bug_timestamp.mpeg ! mpegpsdemux !
mpegvideoparse ! identity check-imperfect-timestamp=1 ! fakesink silent=1 |
grep ident
