TS Doctor 1.0.75: how to interpret WARNINGS statistics ?

I recently started using TS Doctor to check/cut Dreambox DVBS-S recordings with H264 encoding, but I am not quite sure how to interpret the WARNINGS (number) statistics :
- The statistics of an "only check" operation of all my transport-streams (always) show a high number of WARNINGS (see example extract of a Log file : WARNINGS : 10586).
- But inside the Log file I find few/none details about these WARNINGS (in the example extract of a Log file, I see only 1 (one) TS WARNING : a packet discontinuity error at the beginning of the capture).
Hence my question :
- Is there a way (parameter setting ? but I found none) to have more details/explanation on these WARNINGS ?
- I am also puzzled by the fact that the number of WARNINGS in the statistics = number of I-Slices + number of "real" WARNING messages in log file (I verified : all my TS Doctor log files confirmed this "logic") : how can this be explained ?

Hi,

warnings can be ignored in most cases. I guess this warnings are a result of the removing of the filler data. If packets are removed it affects the consistens of the stream. You will get discontinuity warnings because there are packets missing. These warning messages are surpressed because the TS-Doctor is correcting the discontinuity counter but it seams that they are still affecting the warnings counter.

I will try to fix this in the future. At the moment just ignore all warnings without detailed message in the log.
