I purchased Any DVD a couple of years ago followed by CloneDVD2 and Clone DVD mobile. I own an older Compaq computer with an AMD processor, an Hp DVD burner and a crappy old DVD/CD combo unit used as a "reader" unit (faster read rate). When I installed these programs onto this computer, I changed no settings from default and have NEVER had a software related issue. Any problems that occurred were bad discs, either original or bad (cheap) blank discs. Thank you for supplying a high quality product. Too bad every thing isn't this good or easy.
