I know this thread is down the list a bit. However, it seems like a pertinent thread.
I caught a TrammellCast at 9:18 PM. Apparently, my IntelliSTAR failed to cue at the correct time, resulting in a Satellite forecast. Afterwards, during Evening Edition, the IntelliSTAR kicked in, resulting in an overlap of program and local forecast. I have it captured and will soon post it in the "Contributions" section.
