I'm trying to help out a local Historical Society. They have an mp4 video of a reconstructed model of the Gravity Railroad. They would like to be able to use a DVD player to show this and not a dedicated PC.
I must have downloaded 6 different apps to do this and either they want lots of bucks or it does not convert the mp4 to a usable DVD format.

Can anyone suggest a free app to do this since I only have two files to convert. I am thinking the conversion should go from mp4 to MPEG 2 or 3. Am I correct and what would be the groups' suggestion?

Regards,
