I was just curious if the server, once it generates it's thumbnails, can save those thumbnails into the M4V metadata tag itself. I'm also curious if Plex will read the image from the tag if available, rather than trying to generate a new thumbnail.
Lastly I'd like to know if any edits I make in the Plex interface to Genre's for example, will be saved into the M4V's metadata, and if that's an option to enable it somewhere.
Thanks
