Copying Twilight saga New Moon worked perfectly using DVDFab7 beta ver. 7025 in Custom Mode, with pathfinder on, but I had to set the program to copy Title 1, which is 2:10:33 playtime. The program wants to default to Title 12, which is 1:56:04 playtime.
Title 12 will not play past the menu.
DVDFab 6 will not copy Twilight Saga New Moon, but you could rely on version 6 to dependably automatically set you up to a working title to copy in Custom Mode.
Unlike DVDFab 6, if you allow DVDFab 7025 to automatically choose the title for you in Custom Mode, you can't rely on the copy to play. I guess there are still a few bugs to work out of the program.
I haven't used the forum in quite a while and I'm not use to it at all. I hope I am posting this reply in the proper place. I am having problems searching the forum with this layout.
