i think clonedvd and anydvd are hands down the easiest combination, but they’re obviously not free.
you can do it with free software, but it’s going to be a little more work.
also, you can get just anydvd and use it with dvd shrink if you want to go “half free.” and then burn with ImgBurn.
there are a lot of options. you sound comfortable with most of the available programs and familiar with their capabilities. if you’re willing to spend money slysoft’s support for anydvd and clonedvd can’t be matched, and it’s nice to have something that has a responsive support team behind it that will crank out updates within a couple hours of being notified of a new protection or a bug.
if you’d rather not spend money, that’s ok too. dvd fab decrypter to rip to files. load those files in dvd shrink. shrink to ISO. burn with Imgburn. This is a 3 step process, but it’s free so I don’t thnk there’s any room to complain about the extra work really (this is the route I’d go if I was going all free. personally i use the slysoft combo listed above)
