Advertisements That post is 2 years old, so who know what provider Comcast uses now. I know TVGuide used to use Rovi, but there is no evidence that they still do. The example I posted proves that Rovi and Comcast data doesn't match, so how could both be Rovi? EDIT: I checked Comcast, TVGuide.com and TV.com. Data on all 3 matches, but is different than Rovi data. That tells me none of those 3 use Rovi. Here's another wrinkle. Rovi claims to serve both Charter and AT&T, yet those two don't match each other nor do either match Comcast/TVGuide/TV. I don't know what to think now. Is it possible that Rovi generates different data for different customers? That seems like a huge amount of extra work.
