Isn't zap2it owned or maintained by Tribune?
I don't know ....but I would think Not, seeing they do the same thing is some aspects would make them competitors.
edit:
After looking into it a bit, Zap2it is related to the Tribune.
Zap2it is an American website and affiliate network that provides news, photos and video, along with local television listings and movie showtimes for areas of the United States and Canada. The site is produced by Tribune Media Services (TMS), part of the publishing division of the Chicago-based Tribune Company. Zap2it affiliates include Cox, Dish Network, Disney, The New York Times, the Los Angeles Times and The Washington Post.
I notice DISH is listed, but Not D*.
I find this interesting as the Trib has always been mentioned as supplying data for D* ... maybe not.
