PGC edit DIVIDE into 2 discs

[bilbob]

In documentation was written that PGS edit was ment as a substitute to IfoEdit.
I thing that it is far better than IfoEdit by I do not know how to divide one DVD9 into two DVD5, I used to do it in IFOedit because it was easy. Is it possible to do the same thing in PGCedit - How ? I have manual for PGC edit but I didn't found any useful information.

Thanks Bilbo
