and just because you give a program 3 thumbs up does not mean the TiVo will try to record it every time. I think the TiVo tries to record a certain number of suggestions a day. When it builds the list of suggestions it tries to schedule the highest ranked ones first. When you give a program a thumbs up it also gives the actors, director, genre, ... a thumbs up. Ranking is not just based on program name alone.
Be vewy vewy quiet. I am squirrel hunting.
