Whatever happened to the Sacramento Locals in HD? Every time I go to channesl 3, 10, 13, 40 and 58 in the evening after 5pm I get two screens. 1st the transponder screen and then the screen changes to the "we are working on it" screen. During the day the channels snap right up and are working fine. it's in the evening that the HD broacdcasts and OTA disappear. The SD part of their channels do appear during the evening. Should I be concerned or are they "working on it"?
