I have 2 local PBS stations that frequently play the same show - sometimes at the same time, other times at different - but when I set up a recording for a show, it seems to record both instances. I've disabled the second PBS station as a temporary fix, but is there a way to specify which channel, or what time, you want to record the show at?
This may be a holdover remembrance of how my network of ReplayTVs worked - those, you could specify which Replay to record on and which channel at what time, but still watch on any of them. Back in the olden days of DVRs - sigh -
