I have been sent a DVD (size 2.62GB) of TV programs broadcast from a norther hemisphere country*, in which a family member features.
The DVD plays on a PC computer, opening with VLC, and Properties list it as m4V (which I understand is Quick Time file format.)
I would like to make copies for family members who do not have a computer, that will play on standard DVD players.

Many thanks Dougall Stewart. I converted the m4V format DVD to mpg format using Freemake Video converter, and using that program then burnt to DVD. Eureka! It now plays perfectly on my Panasonic
DVD -S33 DVD player. Many thanks. Kia Ora. Denis.
