Though I wouldn't get a pop-up on my TiVo, I only knew about this because DirecTV (last month of service, woo!) is running ads all over their service for it. I haven't seen any ads on other FiOS channels for it.
That said, is there any hope of iN DEMAND running more HD games next season? I've been spoiled by having Rangers games in HD, but I'd gladly pay $199/season for more (all?! :D) games in HD.
