Thought I'd offer up another option for cataloging discs.
Looking for software for book cataloging, I came across developer, Kimico's, Book Buddy, which was a fairly inexpensive full version purchase. It pretty much captured all of my needs to properly log my collection, almost always catching the title from an ISBN scan off my phone, and modular enough to adjust any data you need to for your own preferences. All of that data, by the way, can easily be cross-referenced, sorted in a variety of ways (anything from Title to director to year of release, studio, writer, series, etc), backed-up to cloud storage, exported (and printed), imported and shared amongst multiple devices. You can enter things manually. You can search online, find it, and save it to your catalogue. You can replace any image you want.
I actually thought I was fine with the free Blu-Ray.Com app, but it after a while I found its aesthetic a bit too messy, and off-putting how reliant it was on an internet connection and data usage. And Book Buddy so perfectly matched my needs, I went ahead and purchased their Movie Buddy and Music Buddy apps in a $12.00 bundle (CAD) , and have found both to be just as amazing.
Multiple movies or television shows can found as bundles or individually. I've chosen to log individual releases, amending the info, as needed, and then bundling the films or shows as a "series", which will link them all. Finding television series through their online search instead of scanning also brings up a list of each individual episode and their air dates!
So, just in case I've piqued anyone's interested, all three apps can be found here: https://www.kimicoapps.com/
The bundle came from Apple.
