CoreELEC crashes box when playing 4k movie


#1

I have a 4k movie that plays well under Android on the Nvidia Shield, but crashes the box when using CoreELEC on my Mecool M8S Pro and my Mecool KM8. Both boxes completely power off. I tried running the movie from my Synology NAS and from my new 8 TB powered external HDD, with the same results. All of my Blue-ray Rips play without issue, only this 4k movie causes the issue. Here is the mediainfo for this movie.
