Edited MP4 Files do not show on TV via DNLA

My original MP4 files display fine 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.

Hello,

If you edit a file, it will show up as a new one.
Have you tried re-enabling the media library so the unit pick up the new file?

If not, please try that or try resetting the network drive.
