Edited MP4 files do not display via DLNA

My GoPro MP4 files display find via DLNA on my TV from my EX4100 NAS. But when I edit them and save them, leaving them as MP4 files they will not dislay on my TV. I see no difference between the original and edited version when looking that the metadata. They will display fine via my old Seagate Black Armor, which I am trying to retire.
