I wanted to make backup copies of some family photo DVDs and I found this tool, ISO Recorder v3, very effective. As it says here, "ISO Recorder for Windows Vista/Windows 7 supports CD, DVD and Blu Ray operations. Blu Ray on Windows Vista requires SP2". You just right click on the diskand select an option. I made an ISO file first because I wanted to make multiple copies and that was the easiest. Then I right clicked on the ISO file and copied it to a blank disk. Worked like a charm.
There may be more feature rich tools out there, but for simple copying, I like this.
