This is why I'm asking: Our local FOX station lost power due to a blown transformer during Hell's Kitchen Thursday. They had a slide up that they were having technical difficulties, but a friend said that they still aired commercials. They are reairing it on Saturday, but in SD only. They say they don't have the equipment to show it in HD. But they air things in HD all the time on the normal schedule including Hell's Kitchen. So my questions are, how can a station lose power and not be able to air programming, but commercials play, and how can a station have the equipment to air all the normal programming in HD but can't do a reair in HD?
