Advertisements A DVR is only as good as its guide data. ROVI guide data sucks. Stinks, like garbage. Is frequently wrong. Can't accurately identify repeats. Sometimes can't even identify new episodes. Sometimes can't even give a description of a program or episode. Sometimes classifies one hour documentaries as MOVIES. And I'm just scratching the surface on this topic. EXTREMELY disappointed in what I've seen so far since the changeover to ROVI guide data.
