DVD adapted the MPEG-2 as video standard and AC3 as audio standard. The normal MPEG-2 video resolution is 704x480 or 480p. Usually the movie data of DVD is stored in the .vob file.
MPEG-4 or MP4 is the latest MPEG standard for low-bit-rate streaming video. It is a standard that is suitable for wireless multimedia and broadband applications. Its resolution can be 480p. Compare to DVD video, MP4 requires smaller space with the same picture quality.
