Basically, me and the wife are getting irritated with the kids' ecclectic DVDs and we wanted some sort of Media Player with a piece of software to catalogue the films, preferably with the ability to put the film's cover on. I'm thinking Plex or something like that, but I'm not sure of the best solution. Is getting a NAS and putting Plex on it with all their stuff the best option? I'm not completely sure when it comes to media stuff. I've got a few External Drives, as well as a PS3 and PS4, both with Plex on them. Will an External drive work with Plex well?
