I've been using Fab platinum for over 2 years now. It is the best software of it's kind bar none. I absolutely agree with astone2665 and t0nee1.
The support here on the forum is second to none. Fengtao and Ting are constantly improving the software and adding new features. They also consistently update the software to keep ahead of the curve re: new copy protection.
As t0nee1 suggested, why not try the 30-day-free trial. It's the full retail version, but expires in 30 days if not purchased.
I'm not sure how much you've looked around, but look at a few real user comments about DVDnext copy from popular forums such as cdr-zone and afterdawn. Personally, I'd steer clear.
Good luck and welcome aboard.
