Sure thing DVDFAB,i usually use the customise option first to dump the crap like previews & warnings & trailers then once done either i run menushrink (reduce menu size by removing animations,usefull when dvd9 to dvd5 single disc) or just run straight to split,be sure to have "keep menu on disc 2"ticked on when in split menu window, also use settings to increase dvd 5 setting to say 4475-4480,dvdfab has it's own burning engine called vso (you'll see it on install) works as good as any other burning software,yeah just be sure to use settings to set write speed & whether you want dvdfab splash or black when split disc inserted then away you go
edit: as a trial run i would recommend using dvd rw discs until you have fab setup correctly to the way you want it, i personally use dvd+r media & tick booktype dvd+r to dvd-r,there's no quality diff it's only the type of format of the disc,you'll have permanent free ripping with fab the rest is 30 day trial,other programs i would suggest investing are the three below from slysoft,30 day trial only
It won't always work on some new protections however anydvd usually does then it's a matter of time waiting till fab provides an update,just a heads up no reply necessary
