Irritating issue with USB on a modern TV

[Harlesden]

The problem is with video files.
They all come from the same source and all are in the same file format - mp4.
I've put 136 video items onto my stick. All play perfectly on the computer but only around 30 of the files play on the TV.
The message I get for the others is "Invalid File Type Not Supported" which makes no sense at all as all the items on the stick are mp4.
Can any kind person please suggest a solution?

Are they all the same resolution and bitrate? Are they all MP4 version 1 or MP4 version 2? Does the TV manual say anything about what video types are/aren't supported?

file extension is different from video format.

Check how each video is encoded and what your TV will support.

The "solutions" are :

to either encode all the videos to the compatible format
use a media server if your TV supports that
stream using a wifi device (such as chromecast/firestick)
direct input from computer (hdmi or other connection)

I gave up messing with the codecs etc and fiddling about with file formats and just hook the laptop direct to the HDMI.

Maybe you mean 'MPEG-4 version 1, - that was made obsolete in 2003 so I don't think that there are any TVs around with USB ports that can play video files.
I've never seen an authoritative definition of 'MP4 version 1'. It is a mixup of two different things.

'MPEG-4' is a video compression specification, - '.mp4' is a file extension just like '.mov'.
I need to create files that can play via the USB ports of Blu-ray players for film club showing. I use the MPEG-4/AVC/H264 option in the video editor i use (Sony Vegas). If I inherit a movie from somebody else, I use a free application like 'Handbrake' which has profiles for a number of defined devices (Android tablets, Windows Phone, i-Pad, Apple TV among others and also something titled 'universal' but TVs still don't like that!

Sony TVs/Blu-rays seem to be more tolerant than others, maybe because they also make a lot of video capable imaging devices.
