Speaking of converting VOB to ISO on Windows or Mac, we need to first get to know something about VOB file. VOB files are the core movie files that make up a DVD structure. And it contains all information that a DVD needs to play video, sound, menus and subtitles, however it cannot normally pop into home DVD player for watching with family.
