I generally rip to ISO in customize mode of
DVDFab, selecting the features I want, and then mount the ISO and use DVDFab to split it.
With this new release, it seems to crash the 2nd time I attempt to rip a DVD (rip two DVDs in a row)
It will also crash (even if just run on a freshly booted computer) when I try to split my recently create (using 4.0.6.5) ISO. This did not happen with previous versions.
