 ## [Unreleased]
 ### Fixed
 - Fix `HLS Segmenter` bug where it would drift off of the schedule if a playout was changed while the segmenter was running
+- Ensure clients that use HDHomeRun emulation (like Plex) always get an `MPEG-TS` stream, regardless of the configured streaming mode
 
 ### Added
 - Add `Preferred Subtitle Language` and `Subtitle Mode` to channel settings
