I backed up a few DVD9 movies to two blank DVD+Rs. One of the origional movies got trashed which in this case I'm glad for the backup. Now that I have access to a duel-layer burner and some duel layer media is it possible to place the entire movie back to its origional (the whole movie on the one duel-layer blank from the two single layer backups)? DVDfab split the movie between chapters (disc 1 - Chapter 1 to 13)(disc 2 - chapter 14 to 21). Of coarse at this time I have little knowledge of VOB files and such and I'm not certain if this could be accomplished with just a software app or otherwise. If not than two discs will have to work.
