DGIndex out of sync because of multiple cells?

Hello all

I am using DGIndex to create an index for a Vob file, then process the d2v with Avisynth and in the end, remux everything with ffmpeg.

Now it seems I stumbled uppon a special case where my end-result is slightly out of sync. When I directly convert the whole thing with for example VidCoder/Handbrake, everything is fine.

Uppon further inspection, I found out that the wrong file has around 10 frames more. And uppon even more inspection, I saw that the vob contains two cells or video ids or chapters (no idea to be honest) whereas the second contains the correct video and the first is just a 00:00:00:00.10 long video. When I then create vob file without that first part with DVDDecryptor or with PgcDemux, I get a slightly smaller vob file which is then fully in-sync and also 10 frames shorter.

So is this a case where DGIndex simply cannot be used? I love DGIndex because it's simplicity and CLI functionality.

Many thanks for hints.

Not fully following you. If there is a first VOB that you don't want then just do File/Open and delete that one from the list. If I have missed the point, please clarify.

Not entirely. It is one vob which contains a second very tiny chapter? Video? Cell? ProgramChain? which makes the final product out of sync. If I remove that manually, it works correctly. Is it possible to do this with DGIndex itself or am I dependent on another tool?

DGIndex has no PGC processing so it's unable to deal with that case. If you rip it correctly then that would not be an issue.
