Will DVD Players play MP4 files?

As we know, most old DVD players only support DVD video on DVD disc, they cannot play any video file not to mention MP4 file. Later, some DVD players can play video files on DVD disc. Even later, many DVD players come with USB ports, users can attach USB drive to it, and it can search and play video files on it. However, the video formats they support are very limited. Because DVD video is some kind of MPEG-2 video, this format is supported by nearly all DVD players. MP4 is newer than AVI format, some players doesn't support MP4 but support AVI. Hence, to play MP4 on DVD Players, we suggest you convert MP4 file to DVD-Players-sensible formats like the MPEG or AVI format.
