Why not 3D print something for it? I printed this to make a digital photo frame with a Pi 4 and the official 7" Pi touch display. https://www.printables.com/model/44218-7-touchscreen-case-for-raspberry-pi-4-internal-fan
Printing it with something strong should help keep it safe in an accident though you’ll need to create a mounting solution.
I imagine you’re going to want to find rips of the entire Bluray/DVD and not just the standalone special features. I believe some indexers/trackers will label these “full disc” but I’m not at home to double check that. Definitely sort your results by file size from largest to smallest because you’ll want to be looking at the larger file sizes in your search that include the whole disc, bonus content, subtitles, additional audio tracks, etc.
