Tried to watch Antenna TV tonight and there is a baseball game playing. The guide says Alice but that’s not what is on the channel. What’s going on?
Antenna TV is one of those channels that's a "subchannel" of another channel. My guess is, the "main" channel is also one that usually carries a nearby team's baseball games, but couldn't, or chose not to, pre-empt what was on the main channel, so the game aired on the subchannel instead. (Usually, in a situation like this, it is the main channel's regular programming that airs on the subchannel.)
What's your ZIP code? That way, I can figure out what the "main" channel is for Antenna TV where you live, and try to figure out what happened.
As mentioned, it's a subchannel of a local broadcast TV channel, and it's not unusual for them to pre-empt shows for local programming. They may not always properly pass on those changes to the guide providers like Gracenote that Comcast uses.
