Chapter points wrong after backup.

Hi, I hope someone can help me. I'm not a pro in all this IFOedit stuff, but I'm learning. But here it goes: I've backed up a movie and added my own subtitles. That all worked out well. I updated the IFO files, so I have a newly authored DVD like the original DVD but with my own Subs. The only thing that's wrong are the chapter points. So i tried to edit them manually with IFOedit. All the new chapter points have been edited, so they're like the original DVD. (I used the VTS Overview & the VTS_PGC_1 to correct them). Still the chapter points don't match! I looked at the original DVD and, for example, chapter 6 starts (according to IFOEdit VTS Overview) @ 00:45:35.10, but when i go to chapter 6 while viewing, the chapter starts around 00:45:37.XX.!! Maybe I'm doing something wrong, but could someone explain this to me? How do I find out the real chapter points? I've tried ChapterXtractor, but it failed to give the good values. I also used TSBitCalc, but again i didn't work out. Thx.

Try doing a IfoEdit mock strip. Strip Streams and VOB IDs in VOB Extra but keep everything.

You can get IFOEdit chapter information with DVDDecrypter stream processing feature. Use IFO Mode and set the appropriate chapter info addition at the IFO Mode settings tab. You can add this txt info when remuxing with IFOEdit.

ifoedit is notorious for bad chapter timings in ntsc. try dvdremake
