Easy Disc Burner 

The name of this application is actually very well chosen, as Easy Disc Burner is indeed one of the simplest disc burners that one could ever find. Its interface is close to being completely minimalistic, as its very neat, straightforward, and simple. The interface is actually one single window, from where you can both add the data to be burned onto the disc and tweak the few available settings. Among the available functions and settings, Easy Disc Burner features the possibility to select the writing speed, to enter a disc label, to enable disc burning finalization and to verify the disc after the burning. There are also a few skins available to help you customize the look of the interface. Other than these, there are no other features and options. Creating audio CDs is therefore not supported as well.

Anyway, it allows writing data not only on CDs and DVDs but also on Blu-ray discs as well. It supports various types of discs and disc burners, including CD-R/RW, DVD+/-R, DVD+/-RW, DVD-RAM, Double/Dual Layer DVD, BD-R, and BD-RE.

Considering that it's also completely free, I'd say that Easy Disc Burner deserves at least a try, as, despite its lack of advanced settings and features, it's still a handy disc burner of unparalleled ease of use.
