so here is how it goes:
I have a 500GB SanDisk USB, when I transfer videos in it, the videos work.
after transferring the videos to our Affordabox (basically, like a cable box or DVD box) the videos in the USB still work.
I reinsert the USB to my computer, test the videos in it, and they still work.
BUT when I transfer new videos in my USB after the above mentioned have already been done, the new videos won't work, they will continue to load indefinitely and when I try to play the newly transferred videos in our Affordabox, it would say that it is an unsupported file.
the usb gets repaired if I format it but will have the same issue again if I do the above mentioned
Unable to play videos transferred to flash drive

Once installed MiniTool Video Converter (https://videoconvert.minitool.com), open the program and follow the prompts to convert the video file to a supported format. And then you can just enjoy your video via a usb on Affordabox
