So what I'm doing is downloading an .mp4 video and then cutting and pasting it to the Platforms folder within the Videos folder in Launchbox. I've done this with all my other platforms and respective games (Arcade, SNES, Gamecube, Switch, DS, 3DS, Genesis, Dreamcast, PS1, 2, and PSP) and I have no problems with the videos loading. I'll edit the media on (for example) COD Mobile and when I go to add the video, Launchbox shuts off and it still shows "None" where a video should be.
