Instructions are to press the red button to get English commentary on rugby matches on S4C. I used to be able to do this but not with the Tivo box.
Just tried it and it works fine.
While on the Rugby - press INFO - more down to the SPEAKER and change to WELSH - and you get ENGLISH. Change to ENGLISH and you get WELSH.
The reverse selection is not a fault but a feature of how the switching works - the same happens on Sky / Freesat - when switching audio tracks.
Thank you. I will try that.
