This is one of the must-have tools for all the guys who wish to backup their DVD movies to DVD-R or DVD+RW discs. IFOEdit allows users to parse VOB files, remove and add video/audio/subtitle streams to VOBs, create new IFO files, create DVD images and burn DVD-Rs. All within one little tool. Versions since 0.93 now also include world's first free DVD authoring suite that supports AC3 audio, subtitles and much, much more.
