But my MKV files play incorrectly thru Plex. I’ll have to copy the content to a MP4 file tonight & see if there’s any difference.

In ticket Roku Ultra h.265 content video problems you can see the mediainfo from 1 of my movie files.

I’ll also test your files tonight, thanks for your help.

How do you see BT.709 Header info from the file? I dont see any fields labeled that in mediainfo.
