DVD ReBuilder (aka DVDRB)

I was out surfing and bumped into an app for DVD back ups called DVD ReBuilder. I guess it's been around for a while, but I had never heard of it. I did some research, and apparently it's one of the best apps out there for backing up DVDs and getting 'em to fit on a standard DVD (from DVD9 to DVD5). And there's a freeware version, and a paid 'pro' version with many extra features. Now I have some questions:
1. Has anyone here at MG used this; if so, what's up? Good? Bad? OK? Easy?
2. Why is it not hosted here at Major Geeks? :innocent
3. Why am I just now finding out about this?

For those of you interested, here's their home page:

I was a bit confused by the download they have at their home page for the free version, but if you can figure it out, great. If not, get it here:
