EPGs are part of the standard and broadcasters are required to transmit them, but there's no quality control on them beyond what the broadcaster does themselves; some broadcasters do a great job and some... don't. That's where paid services like SchedulesDirect [1] come in; they pull data from the same source that Tivo and the cable/satellite companies are using, which (usually) gives you accurate scheduling.
