VOB

All DVD movies are stored in on a DVD video disc in so-called VOB files. VOB files usually contain multiplexed Dolby Digital audio and MPEG-2 video.

VOB files on a DVD are numbered as follows: vts_XX_y.vob where XX represents the title and Y the part of the title. There can be 99 titles and 10 parts, although vts_XX_0.vob does not contain any video, usually just menu or navigational information. You can find them on a DVD video disc in a subdirectory labelled VIDEO_TS (all upper case).
