"Plex not direct playing some h265 mkv files - I have a plex server (latest stable from the site) running on a synology ds1515+ and most movies play fine. Is there something I should be looking at?" When I look thru the logs on the server there are no errors, no nothing about the file stopping. But plex has gotten bad, every MKV file now randomly freezes for no reason and forget trying to go forward or reverse. "Why does Plex have so many issues with MKV files? I know Plex is not the only one with this issue, Emby and JellyFin do the same sometimes. Though MKV is in the Plex supported format lists, the MKV playback issues on Plex still come from time to time. Unlike other media software supporting limited media formats, Plex accepts almost any file format you can add to it, with the exception of DRMed sources, ISO, IMG, VIDEO_TS, or other disk image formats. If you want to access movies or TV shows from your computer, NAS or other storage media on a mobile phone or tablet, Plex is a great tool for you.
