Just a comment first - regular DVD players will play mp3 files normally. They will not play mp4 discs.
To burn an mp4 file, treat the disc as a data disc.
Some players would see the data disc and play it.
You can also try using a thumb drive if the file is large. Thumb drives are inexpensive, can contain a lot of data, and are more rugged.
