DVD Lab and Ifoupdate

[filipe_l]

hi, i used DVD Lab to build a dvd with portuguese subtitles,one audio english track and with chaptor extractor ,i imported the txt track to create de chaptors.So far so good.then i update the original ifo with the authored ifo in ifoupdate.then i watched the movie but no chaptors.What i have to do to insert just the chaptors or to view what's wrong with the ifo.Can pgcedit deal with the question??Please help me to fix this.

Why ifoupdating? Are you trying to add original DVD's menu to your DVD after all? Anyway, did you remember to copy the vts_01_1.vob etc (made by DVD-lab) over the originals as last step?
It might be necessary to get rid of all irrelevant lines of chapter file created with chapter extractor, leaving only the essential text (times) to make it work. I have experienced such problem in the past.

yes im trying to put the original menus.Now i have a ifoupdate error telling me that the original ifo dont have a large pgc area.Why?

Probably it cannot be achieved this way.
Here is a guide https://www.videohelp.com/~r0lZ/pgcedit/third_party/blutach/adding_menus_to_dvd_shrink_...hored_dvds.htm
However if DVD-lab is your favourite method of reauthoring DVDs, you could have extracted the menu material with the use of a tool like vobrator (open vts_01_0.vob, select desired menus and save). Then insert the extracted menu clip to dvd-lab and add the appropriate links, while building your custom dvd.
