Matchstick Man VOB ID problem

[dark.soft]

I have ripped Matchstick Man R2 PAL version and I have a problem. I cannot post what ifoedit says because I don't know how to do, but I will describe the problem. Well, I used the guide of this site, and all of the resulting DVD is perfect except a thing. There is a single making of divided in three parts. You can acces to the whole video and then skip chapters, or you can only watch one of three sections of the making of, without the others. The problem is: this pcg uses vob ids 2 and 5. When I use ifoupdate, the pcg's become associated with a crescent number of vob ids (pcg1 vob id 1 etc), and so the original vob id structure is lost. The real problem is that the pcg of the making of is numbered 4, and following the guide, I haven't created pcg number 5,6 and 7, because they are linked to certain cells of the fourth pcg. But now the fourth pcg uses vob id 4 and pcg 5,6 and 7 still are linked with vob ids 2 and 5. How can I solve the problem? Sorry for the not detailed explanation and for my bad english. Thanks for your help.
