Is anyone having problems with the CSN HD feed? Everytime I have watched it the picture is constantly breaking up. No problems with other HD or SD channels. Maybe a MPEG-4 glitch?

Is there a HD feed for Comcast Sports Net in Chicago? I thought it was just broadcasted in SD.
(NEVERMIND)
I just did a little research here...are you kidding me? CSN is in HD on 640? Why doesnt D* inform the customers of this? I was considering the switch to Comcast this year for Cubs baseball in HD on that channel.
