If I'm going to be fair, I'd say probably 3/4 of the problems I've had with Kodi (via OSMC on a Raspberry Pi 4) weren't Kodi's fault. Everyone from Alphabet to WGBH has had a hand in fucking something up. Of the addons I've tried to use, a good portion of them never once worked, or stopped working after awhile because the services they were scraping changed or disappeared. Or, because I am using a Pi 4, high resolution and high framerate can be a problem; I've seen issues with the video playing back slightly slower than the audio track, after 20 or 30 minutes becoming visibly out of sync until it freezes up for several seconds then resumes normal playback. Mind you this is only a problem above 1080p. Playing video files over the network from my NAS works pretty well if a little clunky to set up.
