When editing M3U #EXTINF metadata, treat tvg-id (and related fields) as a canonical identifier: it must be valid, correctly aligned with the displayed channel name, and consistent across variants.
Apply these rules:
tvg-id must correspond to the same channel as the human-readable name; don’t use unrelated or “unknown” ids.tvg-id stable across entries (e.g., don’t mix MeTV+ naming into different id spellings).tvg-id simple and well-formed; don’t invent extra, conflicting attributes.tvg-id incorrectly—use the correct canonical id (or place it in the appropriate list).[Geo-blocked]) in the name.Example (showing the intended shape):
#EXTINF:-1 tvg-id="MeTVPlus.us",MeTV+ (720p)
https://example.com/metvplus/index.m3u8
If you can’t confirm the canonical tvg-id for the exact channel (or its scope), omit the entry’s misleading identifier or use the correct one rather than guessing.
