I've setup a series schedule for Grey's Anatomy episodes to record at 9:00 EST using the First Run Only option. This works fine for the first run Thursday night episodes.
However, in the NYC area, the ABC affiliate, WABC shows previous years episodes late Sunday night (11:35 EST and 12:35 EST) and these reruns are always scheduled as well.
This doesn't happen on other shows like NBC's The Office. Could it be because The Office reruns are on another channel (the FOX affiliate)?
Regardess, it would seem that this shouldn't happen.
