Here we go.. Here's a DIR of the source (bought, ofcourse!)

So what is main? VTS_01 or VTS_02? When using Big3/Scenarist NT, the apps
show me VTS_01 and VTS_02 has exactly the same MPEG2-stream, only different
audio-tracks and subs.

As you can see from the DIR, the source is a DVD9, but the movie is only 1 hr long!!

Why did the manufacturers of the disc not create only one VTS-set when the
total number of audio-streams in the two VTS's are nine, and there is only a total
of twelve substreams in the two VTS'es?

Here's the question: can I remove one of the VTS'es after demuxing the audio
and sub-streams, for then then muxing it into the remaining VTS later?

Cause then there would be no need for re-encoding. (..ooopps.. My calc tells
me otherwise...)

Try doing Big3 on a P4 1.6 with 640Megs of RAM! It takes time, those passes..

All help appreciated! ...and please, BE technical, so I can understand..

Most likely because the total bitrate was too high, and the producer did not want to lower the video bitrate. One VTS likely contains DTS or LPCM audio.

If the video is the same in both vts's, choose the vts that contains the audio & subs that you require. In this particular case i would use vobblanker to remove the vts that isn't needed.
The concept of the big3 is too keep the disc as is, however, your situation is unique, and there is no point in keeping both vts.

Infact, I went over to Big3 NEW+ScenAid for the backup instead.

When the encoindg is finito, I'll pass the script-files, to see if I can get some
additional info then..

Thx for replying - at A.D I haven't got a single reply yet - and I wrote in their forum
before I wrote in this.. :-P

Stick up your good work - your guides are great, easy to understand, and a MUST for
anyone deciding to move frome the 'one-clicker' DVDrebuilder to Big3 to have some
more control over the process! :-D

Mpucoder is more than likely right (isn't he usually? :D). I would also sacrifice one of the vtses, because I cannot imagine that keeping both will result in very good quality. On the other side: it's only 1 hour of video. You could go all the way and completely reauthor it. Put the video into two pgcs with different audio layout (if you want that at all), would require adjusting the menu etc, but if you have some time to spare....

edit: and keep in mind the max bitrate for the video of course ;)
