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.
