Video sync or field issues

Most probably linked to libav* update

Avidemuxed.mkv plays fine on my old PC - that kills any idea about it being broken with older codec/container versions.

If mean is right, then you are stuck with MKVToolnix for remixing these TS's.

Talking about libav, I see that  Michael Niedermayer resigned last month from the ffmpeg team.
I wonder how this will affect that project (and consequently avidemux).

If i cannot reproduce i.e. flag the file as good / bad, i cannot do much

Frame rate mode: is it possible to set option: Variable or Constant?

[mean]

If you re-encode and use the change fps maybe ?

[Jan Gruuthuse]

Re-encoding, only if this is really really needed, (takes to much time).
Still don't understand, while not re-encoding, just re-muxing, this difference (avidemux <> mkvtoolnix) does happen.

[mean]

Constant vs variable maybe
