I will say that it is better than the Sunday Ticket app. I tried watching Red Zone on both (since that is the only thing that is the same) this weekend while I was out on 3G and the Sunday Ticket app would have the sound about 5 seconds ahead of the video. The NFL app was right on and about 50% of the time I had a perfect picture, 40% of the time I had little pixels boxes in places, but still good enough and 10% of the time the picture was not good enough to see. Granted this was streaming on 3G so I am not complaining, I just like being able to have it with me when I can not be at home infront of the TV.
