I was googling other issues and I came across this message.

If you can extract your file to your computer … as a last-ditch effort you can try opening the file in a hex editor. Scroll through the file and look for patterns of anomalies such as a large string of zeroes where you presume are breaks in the file. Delete those zeroes in the file and save as a new file. Hopefully your media player then can play through the footage without hanging up the computer.

Good luck.
