Notare come la vita in diretta era trasmessa con audio fake 5.1. 6 canali attivi ma solo due funzionanti e gli altri muti.
Invece poi la diretta della scala era correttamente in 5.1 sulla 1° traccia audio con tutti i 6 canali attivi e sulla 2° traccia audio correttamente in stereo (solo due canali attivi).
Non ricordo invece se c'è un motivo valido per identificare Rai 4K come "reserved for future use"... Solitamente quando è così è visto come canale dati e non come canale tv. O sbaglio?
