Obviously I won’t share where I’ve gotten my files over the years for media but as a physical collector as well, the prices for some bluray collections of things is outrageous and would like to make my own that look somewhat professional. I have a bluray burner and blank bluray discs.
Buy a 3D printer and print mini “Blu-ray” cases that actually hold a USB stick or MicroSD card. Would still be cheaper than making actual discs.
