While watching BT Sport in HD with the Red button service loaded I get a GREEN goal alter.
Not only does this go to the SD channel to show the goal - but when you return to your original match that is the SD version too.
As I'm on HD to start with - why can't it stay HD for the service?
No - BT box.
All the channels are HD are work fine - but 'goal alert' selected the SD channels - so had to manually change back to HD
I've seen a few reports like this but never been able to replicate it.
Have fed it back to the dev's and will try and work out if there are any edge cases that have been missed.
