So I've been using the multi step way for a while so I'm not new to the process... This app is quite slow, over an hour to process one disk - and for a lot less $$. Also after this lengthy adventure the disk was not good. It would start at chapter 3 and disabled all navigation controls so I can't say what the rest of the disk was like or if Chapters 1&2 even exist.
It's pricey but the one click aspect would be a seller for some, but not if it doesn't work.
