Astroburn seems like a good program. But how do you finalize the disc?
I have checked and installed the application, but it was impossible to locate the Finalize Disc feature which means the software doesn't have such thing. In this case, I recommend using another application from the same category. Access the IMGBurn's page and download the application.
