So I want to setup a QNAP 253D+ as I do not want to pay for streaming platforms however I can't find an app to set it up.
Plex is what everyone is recommending but that requires outside authentication with plex. So if I want to stream from my NAS to the TV I have to authentication with Plex and I want to avoid that. I do not know when Plex is going to decide I can't watch Aladdin on my home system do to racism or something like that.
Permissions would certainly work well enough. I know on my NAS Plex only has access to it's folder. I let it delete things because I sometimes delete things within Plex.
Another secondary measure, back up your Plex files. I do a local backup of the NAS about once a month or whenever I remember. On top of that, most of my videos are ripped from media I actually have so there's that.
