[soroush]

hi everybody
I have a problem with compiling the DVD in DVD-Lab pro
in fact the result of compiling
i did all the neccesary thing for authoring the DVD
but when they had remuxed, in result DVD, video & audio are not synchronized
the black parts in top and bottom of the monitor have gone and the subtitles
are not shown with the movie, but they're exist in right click menu
could you possibly tell me what the problem is
thank you so much for your cooperation in advance ...

What are your source files? vobs from another dvd? or have you converted and made the subtitles yourself?

my source files are from another DVD
I demuxed them with DVD Decrypter & I extracted English subtitle & translated it into my own language
and used in DVD-Lab Pro for compiling & afterward that problem occured...
in fact I just wanted to add my subtitle to the DVD
let it be known that I tried IFOEdit, but it didn't work

If you just want to add new subtitles I would try https://forum.videohelp.com/topic338721.html instead of dvd-lab.
