Load a small, varied media collection into Kodi: films, episodes, subtitles, different audio tracks, and files with imperfect names. Check whether scanning identifies them correctly and whether playback is smooth on the actual device and display.
Then test remote control, shared storage permissions, and the path to rescan or fix incorrect metadata. Keep a copy of the original library and configuration before reorganizing files. The right media setup is the one family members can operate and recover, not the one with the most add-ons.
