 Hello,

 When I try to remux the mpegts file from my TV recorder to matroska, I get
 the following issue:

 }}}

 All the files I've tested fail the same (with or without "-fflags
 +genpts"), always near the end of the recorded program. I suspect some
 data is changed in the stream during the transition from a TV program to
 another, which causes the conversion to fail.

 Here is the sample : http://requiescant.tuxfamily.org/sample.ts

 In my tests, the conversion fails just after Mark Renton emerges from the
 toilet. You don't get anything from the other trailer in the mkv.

 It might be related to #3339.
