I rely on tvguide.com. At the top, there's a choice for listings and then TV shows. You can plug in your local listings. Here in the Atlanta area, I don't have the same channel setup as the main area. I just found the same listings as what I use and it's been dead on for the past three years. If you put your cursor over the show, you'll get a description of the show. It has everything, even Roseanne reruns on Nick at Night.
And Disney is always on ABC.
