Recently had a bunch of channel lineup changes (Time-Warner). Had to re-do guided set-up for new channel lineup & had to delete most of my old Season Passes and create new ones. Now in my To Do list only the new season passes appear (as they should). However, each day I have a habit of checking the Recording History file and I see my old Season Passes with old channel numbers listed there, not recorded, with notation "Not Available. No longer in guide. " It's not really a problem, but an indication that Tivo's OS is not quite getting the info and file information correct. Just curious about it and wondering if anyone else has noticed it. Tivo Roamio Pro Tivo Premier Elite Happens on both.
