The makers of Daemon Tools have announced a partnership with Astroburn, a new free burning application. If you're wanting to get away from the Nero bloatware, then you should give this program a try. The download size is about 4 MB. Like Daemon Tools, it uses the SPTD driver, which requires a reboot when you first install it.
ImgBurn is still smaller and does not require the SPTD driver. However, the advantage of Astroburn is that it has an easier to use interface, so it would be a good program for people who are not exactly computer experts.
And like Daemon Tools, don't forget to decline the toolbar installation.
