There are no conflicts. As far as the Simpsons, that's my mistake. Turns out that there are two Treehouse of Horror episodes airing Sunday. One of them is a repeat and that is the one that won't record.
So I decided to go to the series recording list and delete the series recording for Sunny. I then went back to the grid and tried again to set a series recording and this time it worked. I also set one for American Horror Story without any problems. Guess it was just a glitch of some sort.
The guide data for Sunday, Oct. 7 for FOX wasn't accurate. Remember the two Simpsons episodes I said were listed, it was changed to only one but it was listed at Treehouse XXII when it should have been XXIII. The Cleveland Show was listed twice, but the second listing was actually Bobs Burgers. No wonder the DVR had problems recording.
