the creation of ISO with free dvdfab decrypter will now use Ner0 or ImgBurn [not VSO as this is a paid program]. dvdfab no longer will create ISO internally.
[B][U]this may not get worked into the next release but it is on the to-do list.[/U][/B]
if you really need ISO for you projects you can still rip using DVDFab and open ImgBurn in Build (Image File) Mode. then select the DVDFab output Video_TS folder as source.
