From the Official Site :
ImgBurn can write most types of CD / DVD images and it supports all the latest writers (including booktype / bitsetting on many of the major ones - i.e. BenQ, LiteOn, NEC, Plextor, Sony). You can even use ImgBurn to erase / format your rewritable media!
ImgBurn will try its very best to burn your DVD-Video double layer images using the layer break you've specified in the IFO files, but it can also calculate the best place for you, to save you the trouble.
Advanced functionality can be found in context menus that appear when you right click on various bits of the user interface. Can you find them all??!!
