Just been watching it didnt realise it kicks in till kick off. Sound is fine for me. Just been comparing the HD picture from freeview with the iplayer UHD. Looks quite good the pitch detail you can see a difference and you can see quite a big difference in the Aussie yellow shirts on HD the yellow is more blurred as though the sun is reflecting off the shirts but in UHD you can see the detail and little shadow of the shirt creases. My son is watching flaming Youtube again too which doesnt help but will definitely try this in future.
