My issues have gotten a little better, there are times I can lock into the HD signal with no problem. Signal ramps up in about 30 seconds and stays there. Other times picture quality varies throughout movie/TV show. This weekened I watched an episode of Star Trek TOS and 30 Rock with a signal locked in HD. The one episode of BBC's Wallander was all over the place picture wise throughout whole episode; from Low/SD to High/HD and all over the place.
