Any movie or TV show that was filmed on FILM (not video tape) is actually a higher resoloution than 1080p or 1080i
True, but the basic point was valid... having 1080p output would only be worth it for 1080p programming (currently consisting of one movie)... for regular programming, it's being broadcast in max 1080i, which a panel would convert to 1080p for display anyway (and likely do a better job at it than the receiver).
