There is also good coverage of this league's games on S4C......saves travelling to Wales. I believe that the subtitles are in English (commentary in Welsh).
In England, Scotland and Northern Ireland, S4C is available on Sky 134, Freesat 120 and Virgin TV 166. S4C is available online and on demand at s4c.cymru, BBC iPlayer, YouView, tvcatchup.com, TVPlayer.com and other platforms, throughout the UK, and can be accessed through the S4C App for Apple and Android devices.
