+3. In your IPTV client or **Plex DVR**, add playlist URL: `http://<host>:8080/playlist.m3u`
+
+Each channel in the M3U points to a **continuous live stream** (`/live/<id>`): FFmpeg concatenates the channel’s randomized videos into one MPEG-TS stream and loops it, so Plex can tune and record like a normal TV channel.
 
 ## Endpoints
 
 - `GET /` — simple web index with playlist link
-- `GET /playlist.m3u` — master M3U (all channels)
-- `GET /channel/<id>/playlist.m3u` — single channel M3U (randomized, no adjacent same show)
-- `GET /stream?path=movies/...` or `path=series/...` — stream a video file
+- `GET /playlist.m3u` — master M3U for Plex DVR (one live stream URL per channel)
+- `GET /live/<channel_id>` — continuous MPEG-TS stream for that channel (for tuning/recording)
+- `GET /channel/<id>/playlist.m3u` — single channel M3U (list of individual video URLs)
+- `GET /stream?path=movies/...` or `path=series/...` — stream a single video file
