Basically, there is no need to do 'embedded' subs.
But I am only conversant with the process in Linux.
In ANY case, re-authoring is required, as adding 'embedded' subs makes the
files bigger.
I would do it this way (leave menus out for a moment):
cat partial vobs together in one title so it is one long vob.
Demux the VOB into mpeg2 and AC3 or mp2, and bitmaps (subs).
This will also create a .sub timing file.
Edit the mpeg2 and audio separately (I almost ALWAYS process audio separately),
Edit the .vob timing (and bitmap reference) so the subs you do not want are
out, and the rest is shifted as needed.
Mux mpeg2 and audio to a vob.
Use submux-dvd to add the subs again (as real DVD switchable subs) to the vob.
And then use dvdauthor.
You can of cause render the subs in the mpeg2 too, but that requires re-encoding,
and then you cannot switch these off.
But I think all this is not much help to you.
I do not understand that your 900 MHz PC cannot do preview, I can do that 2 x
almost on a 950 MHz Duron in full screen.
For your situation I would first try to find out WHERE the audio goes out of
sync.
Perhaps in the menus?
It is really needed to demux and re-author in my view, and edit both audio and
video, make new menus.
Maybe there are other ways, but I dunno in MS windows.
For some Linux stuf see http://panteltje.com/panteltje/dvd/
I wrote a small program a week or 2 ago to embed subs in a ripped VOB
http://panteltje.com/panteltje/subtitles/ the sub2ppml, that then can
be used with transcode subtitler to make AVI or DVD or whatever.
It takes the DVD bitmaps and makes a .ppml control file, then renders the
btmaps in whatever output format you use (in transcode).
There must be a million ways to go about it.
I will leave it to the MS windows experts here to help you in your OS.
