A VOB file (Video Object) is a container format contained in DVD-Video media. VOB is based on MPEG-2 program stream format, but with some additions. It contains the actual Video, Audio, Subtitle, and Menu contents in stream form. If the VOB file extension is changed from *.vob to an MPEG-2 type file extension such as .mpg or .mpeg, the file is still readable and continues to hold all information, although most MPEG-2-capable players don't support subtitle tracks.
