Question: will dvd players play mp4 format?
Answer: Previously, MP4 always employs divx or xvid, which can be played on DVD players. But at present, MP4 always applies H. 264 which is unaccepted by DVD player. So if you really need to play MP4 on DVD player, you can try to convert MP4 to MPEG2 which is natively supported by all DVD players.
