Dolby Pro LogicI/P/B
A surround system where a 4-channel audio track is recorded as MPEG 2, the video compression standard adopted for use with DVD-

These are uncompressed digital signals, similar to those found on CDs.
Film and video
DVD-Videos are recorded using either film or video. Usually, film is
recorded at 24 frames per second, the rate movies are filmed at, while
video is recorded at 30 frames per second.
