MKV files wont' play. Tried everything!

I have 50 .mkv files in one set that won’t play. They play on my computer of course and I’ve tried everything: changing the compression for all tracks to “none” in mkvmerge, running it through mkclean and mkWDclean, I’ve even tried changing the extension to .mp4 which has worked on other files. Nothing has worked. Every time the file just says can not be played and after using mkclean it just loads forever then won’t play anything else. I restarted the device between every attempt. Here is the info from one of the files:

High 10 does not work on this player. You would have to totally re-encode them in order to play.

Can I assume that they are internet downloads?

yeah they are fan subbed videos from a japanese show, unfortunately the only set of videos available so i will just have to watch them on my computer or re-encode them.
