When setting up a season pass for a local PBS show, the channel selected is one not enabled in the current channel map, but is in the Guide.
In this case, the PBS show is on two local PBS channels at the same time in the Guide on 28.1 and 56.1. The show selected for the pass is 28.1, which is a disabled channel due to poor reception. It should be choosing 56.1, but nothing I can do will make the system take this choice.
It appears that when you do a search for a show, you’ll get returns for channels which are both enabled and disabled in the Guide.
