I've noticed that some 3rd party programs have issues with opening the MP4's.
As for the investigation part which should be able to be reproduced.
I used Davinci Resolve (free version) to see if this program would have problems with opening the MP4's.
And most of the MP4's where not recognised; showing an error message.
Using FFmpeg and BOX4, I re-container the files (mp4 to mp4); no re-encoding.
Compared with MediaInfo for differences after the re-container process.
These are the main things that changed, which could cause this issue.
It's not many programs that have problems opening them, but I wanted to mention it.
Maybe one of the developers can have a look.

Code:
Original:
Codec ID: isom (mp42/mp42/iso6)
Re-Container:
Codec ID: isom (isom/iso2/avc1/mp41)
