Whenever I try to watch (HD chanel 576) Washington Capitals games my tv glitches - often goes to black screen, or on delay, or is pixelated. I just got a new router from Verizon - but it isn't helping. The three game losing streak is painful enough....but watching in low def is even more insulting. I want me HD to work. I have tried the unscrew cables and try again...this is not a new problem....but I am kind of over it now.
