This is fairly simple for movies: use the title of the film, followed by the year it was released. Plex and Kodi can add movie posters and other information to your content, but only if you name your files in a way the applications can understand. That's the advantage of owning your own content without any pesky DRM. Of course, once you have a collection of movie files, you can use whatever software you want and try out something different whenever you want.

By comparison, Kodi is completely free (and open-source), but it's not as seamless of an experience as Plex. There's also a Plex Pass subscription, which removes the need for the in-app purchases and unlocks other features. Plex allows you to create a server and watch content from it with the web app (or TV apps) for free, but if you want to watch your movies using the mobile Android or iOS apps, you'll have to pay an in-app purchase for each device. Once you set up a server for your movies, any other devices on your local network with Kodi installed can play the content. Kodi is an open-source media center application, with plug-ins available for playing content from a wide variety of platforms and services.
