I just got a new HDTV and noticed for the first time that Fox News HD and Fox Business HD are in 720p while CNN and CNBC both are at 1080i. Frankly it is quite noticable and CNN looks quite a bit better. Why is Fox News at the lower resolution? Does it save DirecTV money to carry it like that or was that a Fox News decision? And how does Fox benefit from the lower resolution? What other HD channels are really at 720p?
