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?
What other mpeg4 to DV conversion program do you recommend?
