I live in the San Francsico Bay area and recently had a CM4228 installed along with a DISH 622. I receive all my channels here in the Bay area very well most of which are from Sutro tower. I do receive some from San Jose with my current antenna position. All other stations from Sutro look great in HD but I noticed that when viewing KRON 4.2 in HD that the picture looks stunning with still or low notion on the screen but when the movement of the objects on screen get faster or the camera is moving quickly I get a lot of breakup and pixelization. What would cause this? Is this a problem of multipath or is it on KRON's end?
