Start with the intended collection
Decide what the list should show before opening the editor. For example, you might want a subset of your own movie library with a particular tag. This is a library query, not a source of new media or a replacement for a viewing subscription. The official wiki explains that accurate results depend on a correctly scanned or scraped library.
Choose one applicable media type
The documented editor is reached through Music or Videos and then Playlists, where New Smart Playlist is offered. Select the appropriate media type before adding rules, because available fields depend on that type. The wiki does not permit arbitrary mixing of movies and television shows in one smart playlist; its special mixed category concerns music and music videos. Keep that boundary in mind when designing a collection.
Check all versus one-or-more logic
With several rules, the choice between matching all rules and matching one or more changes the result. Suppose a hypothetical movie list asks for a chosen tag and a chosen year. Requiring both produces their intersection; allowing either produces a broader set. Test the individual rules against known library items before adding more conditions, rather than trying to fix an unexpected list by changing video-decoder settings.
Verify metadata before revising the query
If an expected title is missing, inspect its library metadata and chosen media type. A spelling difference or unpopulated field can explain a failed match without any media file being lost. Give the playlist a clear name and compare its output with a small set of known items. Menu details can vary by skin and version; the linked official pages remain the reference for the installed environment.
