Many versions of the 5 app have live feeds of the following channels available:
- Channel 5
- 5USA
- 5STAR
- 5SELECT
- 5ACTION
To start playback, navigate to the Channels/Live TV section of the app menu, select the relevant channel and then press the play button at the top of the screen.
Note: Unfortunately you cannot use Chromecast to stream live channels, so you will not see the Chromecast icon.
