Still have to find a substitute for DVD2one. I could just boot up Mojave from an external drive (holding the alt key makes it easy to switch between the two OS's) but...
First learning curve I've been on for four years.
I briefly looked at the old DVD2one website to see what it does. I don't know which features from it you use, but check out
Handbrake. It's free (but still
very good quality software). It might be able to do what you need.
