I sure miss the old versions of Nero. I use to remember when I could download the parts separately, e.g. Nero Burning ROM was a separate package to the Nero Vision, InCD, etc. Also, the Nero Burning ROM download was ~15MB, not several hundred megabytes! I stopped using Nero after version 7 once it started coming bundled with desktop add-ons, toolbars, etc.
The two I mainly use now are ImgBurn and Cheetah Burner.
ImgBurn is a must-have, freeware, a tiny 5MB download and will cover most if not all your data burning needs. E.g. it writes files, songs, disc image files, etc. verifies and can also create images from CD. It also has a very wide range of technical options for those who need control over how it writes to disc, the file system, Interface settings, error handling, etc.
Cheetah Burner is a commercial product (~$20) and also quite compact (<20MB). While it lacks the technical options of ImgBurn, it's the closest I have to what Nero was like and still easier than Windows' own disc burning method. I.e. tiled window for building the compilation, can verify, write to CD, DVD, Blu-ray, etc. including multi-session and can burn MP3s to audio CD & videos as a Video DVD.
Sure if I want to create a sophisticated menu based DVD, edit home movies, etc. I get a video editing package (e.g. Corel VideoStudio.) I shouldn't need to be forced into getting a bloated "all in one" resource-hogging suite if all I want to do is everyday disc burning.
