Fit more movie into DVD-/+R by DVD2one?
 

Hi there,
I am trying to join the VOB files of 2 movies and feed into DVD2one, but I don't understand some points, as suggested in "IfoEdit" website:

Joining double sided DVDs:
---"First you need the check out, which is the last VOB-ID on side A. So load VTS_01_4.VOB of side A into VobEdit, and scroll down to the last Navigation Pack. The last VOB-ID in that case is VOB-ID Nr: 2
Okay, so the file VTS_01_1.VOB of side B must start with VOB-ID: 3"

I believe the above principle also applicable to 2 movies joining together, I tried and I did not see where the "Navigation Pack" is located. I know I have to create a NEW IFO after joining but I don't know how VOB-ID works. Let's say, DVD2one transcodes 2 movies, how can we reach the 2nd movie (by pressing "next" button?).
