I have a Series 3 TiVo and every once in a while I will create a Season Pass and the Season Pass will not display the show name. Just the channel. Then when the shows record and there is more than one of them, the folder in Now Playing will not show the show name, either, just the number of items in the folder. (If there's only one show recorded or I view without grouping, then I see the show name, but when sorted by name the show sorts at the end of the list.)
One current example of a program showing this problem is Pawn Stars on The History Channel.
I've tried deleting and recreating the season passes. I'm not sure what else to try without deleting everything and starting over, which is way too painful.
Has anyone else fixed this problem?
