 explain how it can be reproduced.

 Hi cehoyos,

 I'm not a developer, so I can't provide a patch. However, I think the
 problem is well described: when generating M2TS files the result is not
 conformant with the Bluray specification because the PCR marks are
 included in the video PID, instead of inside an alone PCR pid.

 How to reproduce it? Easy, create one m2ts file: "ffmpeg -i test.mp4 -bsf
 h264_mp4toannexb test.m2ts". Then you will see that the PCR marks are
 incrustated in the video pid 0x1011, and not in the expected pid 0x1001.

 Futhermore, cus has provided a patch (Thank you man!):

 Please, check it.
