Many times when I turn on our TiVo, it's recording Spanish-language programs.
Or more specifically: it's recording Spanish versions of movies or TV shows that I enjoy. And so the dilemma is, if I thumbs-down the program, is it going to influence my taste for the original English program, or only for the Spanish? For example, if I thumbs-down "Harry Potter y el compartimiento de secretos", is that going to unduly display a dislike for fantasy films about a young wizard and his trials at boarding school? It's quite vexing.
