Advertisements It is difficult to spot-check and find problems with Rovi data, as the problems are sporadic. I currently use WMC with Rovi data, and do still have issues that I believe are related to Rovi (as opposed to Microsoft's poor import of the Rovi data in to WMC). An example of an issue that exists right now is with "Storage Wars" on A&E. There are several episodes called "Barry Strikes Back" which are all different episodes (although they all have the same episode name). Rovi sees these episodes as all the same episode, even though they are three separate distinct episodes (and actually sees them as the same as an episode that aired last season, so WMC will not record any of them, since it thinks it already recorded them): 4/5 9:00pm ET 4/5 9:30pm ET 4/12 9:30pm ET It appears that Gracenote does not have the same problem with these episodes (you can see that they have different unique episodeIDs on zap2it: EP01341345-0216, EP01341345-0218, EP01341345-0230). I'll admit that having several episodes in a series with the same episode name is unusual, but Gracenote appears to be able to handle it, Rovi cannot (at least not consistently). This is not something you would notice by looking at the web sites that provide Rovi listings, such as tvguide.com or roviguide.com as the metadata that is used is not displayed on those sites. I've also had problems with Rovi data where some episodes of a series are not associated with the series, so that they will not be recorded with a "season pass" (in TiVo jargon). Often this data is corrected before the episode airs, but sometimes it is not (although I'll admit that I have not seen this problem within the last month or so, at least for the shows I record).
