I appreciate the response, and as i said, I understand that jellyfin is completely accessible from PS4 even though there is no dedicated app. Unfortunately, that's not an option for all the users in my household, which is why I'm running both a JF and Plex server.

As far as PS4 not being designed as a streaming device, the fact remains that it does stream media, and since I have it in my house, it does serve that purpose when it is not being used for gaming. I'm not ruling out the option of adding a dedicated streaming device, but I am loath to the idea of trading in one data harvesting service (plex) for another.
