Perhaps your local ABC is having a problem.
I would reprogram my digital channels because it should remap to = your local ABC channel #. My local ABC is 6 but I find the DT signal at 42.Then it remaps to 06-1.
My local ABC, NBC and FOX only broadcast in digital (480?).
My local CBS is 24/7 HD feed while local PBS has about 5 broadcast in digital and 1 other channel in HD whenever there is HD content being broadcast.
Came in great in SoCal.. Thought I am really getting tired of Doc Rivers east coast slant. Jeeze, they really need to give him the boot. Listening to him on 5.1 tonight was very painful.
