My wife has a title keyword wishlist for "Downton Abbey." It is set for "new & repeats," and "get only in HD." It is very close to the top of the 'recording priority' list (so tuner conflict is not the issue).
The show is on Sunday nights. At 8pm they replay the episode from the week before and at 9pm they play the new episode. For some reason the new episode was not recording last night. My wife turned on the TV in the middle of the episode and realized it wasn't recording, so she promptly tuned to the channel and hit record to at least get what was left of it. I tried to do a little trouble-shooting and found the following:
Guide info appeared fine. The title was correct and it was listed as being "new" with a first aired date of 2/16, and 1080 resolution (so I assume it met the HD requirement, as usual).
Season pass manager -> upcoming episodes: showed the two episodes for next Sunday and it had the 8pm replay episode marked as not going to record because it was a duplicate (presumably because my wife had hit record on the episode that was currently playing, even though it was a partial, so TiVo would not automatically record the same episode again next week). The 9pm 'new' episode for next week was marked to record as I would expect.
History: Not much listed for the day in question. It just shows that it did not record the 8pm Downton Abbey replay episode because it was a duplicate (which it was, from last week).
I'm kinda baffled as to why the 9pm episode didn't automatically record. My only hunch is that it might have something to do with the "only record HD" setting. I originally set that because PBS was playing some of the episodes on both their HD channel and their non-HD channel and I wanted to make sure TiVo would record it from the HD channel (because when left to its own devices it had recorded the non-HD version once or twice).
Any ideas or suggestions for further trouble-shooting would be greatly appreciated!
