Seriously frustrated! Our Penguins Center Ice Beta was working fine until last week; now, about 5-10 sec after connecting to the channel, the screen freezes, and we can't watch the game at all. Since we pay extra for this, it's getting extremely frustrating, needless to say. Some other team's Center Ice Betas come in fine, although others freeze, as well, or even are a blank screen. Xfinity, what the heck is going on, and PLEASE FIX THE PROBLEM, SOON!!!!
