Same here. There's been a few times when my wife turns the TV on and sees an interesting special on. She'll hit record, but if the show started more than a half-hour prior, then the Tivo can't get all of that show even though the tuner has been on that station the whole time. Because the shows in question tends to be non-repeating specials, we discover them spontaneously. It's not as if I can set up a wish list for that. For the situations we run into, a 1-hour buffer wold cover most of them.
