It's not used by many people here as I've not heard it mentioned before , but I have just read a little of the faq. and it doesnt appear to be anything great at all. I'd suggest using DVD Shrink with whatever burning software you have... DVD Shrink being free , guide here: http://www.dvdshrink.info/guides.php
I bought this program and it's a rip-off. There is no burning program or any other program for that amtter. All this does is tell you where you can go to get programs that you probably already have. They will only give your money back if it won't run on your computer. It also has some guides that are widely available for free. Stay away from this one.
