Won’t make a difference, if the TV doesnt support it the tv doesn’t support itLol, so you have to do X/Y/Z and then...it doesn’t work? Sorry, couldn’t resist!
So we can record glorious DV HDR on our new devices, but to play it, forget the (current..) ATV, as it wont play.
A new ATV must be coming, or else this is a kind of big omission!
