I already made the mpeg2 and AC3 and they both in excellent condition... the sound was out of sync by 0.782 sec so I stretched the audio that amount and is synced now... I notice when I added the AC3 that the project size jumped from having 400MB left to a deficit of almost 2GB! and the AC3 is only 400MB so I want to know WTF is dvdit trying to do... I already finished making the chapters and I can't go on because of this inquietud.
I never used DVDIt, but I would suggest you to use IFOEdit which is free (DVD Author____Author a new DVD).
(1) Load the video (*.M2V);
(2) select the audio (*.AC3 or *.MP2). After that, click on the audio stream and tell IFOEdis which language it is and, if it has one, insert a delay (if the audio should be is in-sync with the video apart the constant delay. If the audio needs to be stratched to be always in - sync you won't need to add a delay).
(3) loat a chapter file (an ASCII file named, by default, Celltimes.txt, containing the chapter position (in frames).
For instance, for a PAL DVD (framerate = 25) you'll have a file made like:
7500
15000
....
to have chapters at 5', 10' etc. (7500 = 25 fps * 60 sec * 5 min). If you have the original DVD, you can extract exactly the chapters position by loading the movie's IFO and giving the command Tools___Save celltimes to file .
Thay application is simple. I don't know why DVDit didn't understand that AC3 stream (unless it was an illegal stream and it needed to uncompress it).
In this case, IFOEdis will not mux the audio to the video, in the resulting files. Look, on the starting screen, if it shows that it understood the audio.
Otherwise, to see if the AC3 is uncorrect, load it with HeadAC3he and see if some errors arise. Otherwise you can re-convert to AC3 with FFMPEG GUI...
