ImgBurn

ImgBurn writes a variety of DVD and CD images (including ISO images) to your CD / DVD writer, and is able to handle things like booktype and bitsetting. It is also able to burn DVD Video double layer images using the layer break you specify in the IFO file (or it can calcuate the layer break for you if you wish). ImgBurn is also able to erase and format rewritable media. Other features include the ability to create your own ISOs, with support for the various ISO levels, Joliet support, UDF, bootable CDs and DVDs, etc, from files and folders on your disk. In other words, you can basically use this program as a CD/DVD mastering program.
