Chapters and lenght decrease after authoring

[Lautaurus]

Hi gurus !

I've having a problem for weeks that it's driving me insane .
I'm trying to backup LOTR extended D1 (1h45min aprox, 28 Chapters).
I demux all streams with VobEdit (also tried SmartRipper), and then author with IfoEdit 0.95 getting mp2v file ( > 4Gb), DTS stream and subtitles.

After following all the steps ( copying/pasting subtitles' color, Get VTS Sectors...) I end up with a IFO that says the film just has 1h23 min and 23 chapters ! I can see all the movie in the PC, but when playing in a standalone the movie freezes after five seconds.


I've followed the guides step by step dozen times, but I still don't know what I'm doing wrong

Can anybody help me?

I found the problem : VTS has 2 PGC, PGC1 has 23 chapters and about 1h20min, PGC2 has 28 chapters and 1h46m.

How do I demux the video/audio/subs just from PGC2 ?

Any help appreciated
