xmltvdb creates a database from a set of xmltv listings and then provides a Web interface to view the TV listings in a grid format similar to many Web-based listings providers, but with user customization and no advertising. It supports explicit and bayesian classification of shows to highlight items you like and de-emphasize ones you don't.
