It’s been great, but Plex has steadily changed in an unwanted direction. It can also transcode and stream media in multiple multimedia codecs to ensure compatibility with all types of devices and screen sizes. Plex can neatly organize media, fetch metadata and movie posters, and keeps track of what and how far you’ve watched your media files. It’s been my primary way to catalog and watch my movie and TV show collection. So be mindful, plan or split up into manageable parts.I’ve used the Plex Media Server for over a decade.

I just came across this as I was trying to figure out a better way to ensure matching for things and with the new agents, you can use the IMDB/TVDB ID as part of the name to ensure it matches right.
