Apparently, Rovi Program Guide data does not list science fiction as the genre in the program descriptions for science fiction shows. This came to my attention earlier today when I was using the TiVo Program Guide and set the filter to Science Fiction, and nothing resulted, despite the fact that there was something like 6 hours of Star Trek half-hour and 1-hour shows scheduled for the day from 6 different Star Trek series (Star Trek, Star Trek: The Animated Series, Star Trek: The Next Generation, Star Trek: Deep Space Nine, Star Trek: Voyager, and Star Trek: Enterprise). In checking the shows' Guide data individually, it appears that none of the shows has a genre setting set, to anything let alone to science fiction. Really, Star Trek? Probably the most successful science fiction/fantasy show of all time? C'mon, Rovi.
