 Replying to [comment:188 pdr0]:

 May I respond here?

 > As for the other issues, eg. the 1st frame in coded order specifies a
 frame_num of 227 and pic_order_count_lsb as 362 in this 99 frame sample...

 Oh, dear. Where can I see that, and how can I fix it? ...You see, I don't
 know how to parse M2TSes.

 > another issue is the values are supposed to increase in decoding order
 according to the specs, but there are examples where they  decrease.

 Oh, dear, again. Decreasing DTS is obviously very bad. I thought I checked
 every DTS. Can you show me where in my composite listing DTS decreases (or
 just give me the DTS value).

 Despite all that, I still don't see why showinfo and show_frames report
 DTSes & PTSes that don't exist.

 Thanks -- Mark.
