Guide for backing up my DVDs on a Mac ?

[Sossity]

I was told that there are screen shots made as a guide for me for backing up my dvd's, & I was going to have an advanced guide.

So far I have been given steps

1. use dvd fab dvd decrypter to copy the dvd's, I would still like some detailed outlines for all the settings to use in this.
2. Use any iso lite or image burn to make the .iso files, & outlines for all the settings for these as well.
3. I will have all this content on a 1 tb external hard drive.

Apologies if I am rushing, but the new school semester will be starting for me in about a week and a half, & once my classes start, I will not have any time for dvd backups, so I would like to get most of it done while I am not snowed under with school work.

The Mac version of DVDFab is fundamentally broken, and cannot be supported by us at this time.
There's absolutely zero way to reliably use an OS X computer to copy/backup DVDs as ISO files at this time.

You'll need to use a Windows computer for this task.

I wish I had better news for you, but the attempts to create a Mac based guide have failed over and over again. (Aggravating. )

For example, this was today's most recent stupid/obscure error thrown by DVDFab:

You must be logged in to view this content; either login or register for the forum. The attached screen shots, before/after images, photos and graphics are created/posted for the benefit of site members. And you are invited to join our digital media community.

If you want a Mac based solution, you'll simply have to wait around for DVDFab to upgrade their software, which doesn't seem to be a priority based on their responses to bug reports in their forum. Given how Mac is a niche platform, I would imagine 95% or more of their sales is tied by Windows users.
