My DirecTV Guide still shows NBC and ABC digital channels, but their programming says "OFF AIR". Should I be seeing a black screen or something on these channels (like regular cable channels show colored bars when they're off the air)? All I get is "Looking for signal..."
The reason I ask is because I just installed my antenna for OTA HD last night, so I have no idea whether the signal isn't reaching me, or if there is no signal at all.
Thanks.
