I want to be able to make perfect images and/or copies of any CD or DVD, movie or music or data. I was using Nero to create images until I ran across some that would not work. I would prefer freeware, but am willing to buy software. I would also prefer a non-proprietary image file format (not .nrg, .ccd, etc; rather something like .iso). If being able to create and/or burn these images is more complicated than just clicking a button, please inform me or point me to a comprehensive tutorial. Any information is helpful. Thanks much.
