-**Q:** Why doesn't my HLS content work?
-
-**A:** If your HLS content uses MPEG2-TS, you may need to enable transmuxing.
-The only browsers capable of playing TS natively are Edge and Chromecast.  You
-will get a `CONTENT_UNSUPPORTED_BY_BROWSER` error on other browsers due to
-their lack of TS support.
-
-You can enable transmuxing by [including mux.js][] v5.6.3+ in your application.
-If Shaka Player detects that mux.js has been loaded, we will use it to transmux
-TS content into MP4 on-the-fly, so that the content can be played by the
-browser.
