As I understand, there are no sync issues because you are using eac3to to demux (eac3to fixes sync issues).

This means that when using mkvtoolnix to load the bluray playlist directly there will be sync issues?

This is what I get in the output with Makemkv on the Avatar extended cut:

Too many AV synchronization issues in file 'C:/video/Extended_Collector's_Edition_Disc_1_t02.mkv' (title #3) , future messages will be printed only to log file

This is up to 80% of the remux, more is in the log for the last 20%.

@ Mosu

This happens with all of the seamless branching blurays.

I have now also tested remuxing this by loading the playlist directly in mkvtoolnix: it shows absolutely no information regarding audio skew or dropped frames.

I understand this means mkvtoolnix has a sync issue when seamless branching happens?

Until this is fixed, shouldn't the output display a warning that the resulting mkv will have sync issues to at least let the user know?

Thanks.
