Expired deleted shows come back?

It shouldn't do that if you've watched the episode already (I seem to recall the cutoff is if you've watched more than 5 minutes).

But if the TiVo is forced to delete an unwatched episode it deliberately doesn't count that under the 28 day duplicates rule. So any season pass or wishlist will not consider additional airing of that episode a duplicate and will try to record them. (If the SP or Wishlist is set to First Run Only, it will only attempt to record airing for up to 28 days from when the guide data claims it first aired (Original Air Date))

 

Are you claiming that the 'original air date' amount is different in cases when the Tivo deletes it and when the original showings can't be recorded due to conflicts?

In other words, I could swear that in all of the threads, people talk about 14 days as being the length of time a first run will count.

 

The TiVo doesn't have the concept of watched or unwatched when it comes to deletions. If it pushes a show off the NPL due to space it resets the 28-day rule on that episode so it may re-record it.

 

I've also heard people claim 14 days for First Run. But I sat down and tested it and confirmed it was 28 days.

(Found a new episode of a show on the Disney channel that repeated about once a day for over a month and kept scheduling other shows to conflict with it to see when the season pass would stop rescheduling a later airing)
