Comment (by markfilipak):

 Replying to [comment:15 Balling]:
 > This stream is even worse, pdr0, as it has PTS of zero on I frame ...

 Huh? The first PTS is 504137396.

 > ... but two first B frames should have smaller PTS, as they are
 presented before I frame and since they cannot be fully decoded actually
 are just dropped, and are later used for decoding of another, third, B
 frame. LOL

 I think you're looking at Ticket_11055.m2ts. Look at Ticket_11080.m2ts --
 I removed the 2 B-frames that were between I's DTS & PTS.
