I get similar messages on all or nearly all mpeg2ts files.
Even ones with minimal artifacts.

I have seen mpeg4 files which did not generate any sort of warning/error
messages from ffmpeg, yet had massive problems.

Where is the secret decoder ring for deciphering these warning/error
messages?  (e.g. what exactly does ffmpeg think is wrong with the file?)

What other mpeg2ts to DV conversion program do you recommend?
