Saw this article on NY Times. "DVR, Once a Mortal Foe, Is a Friend After All" (http://www.nytimes.com/2009/11/02/business/media/02ratings.html?_r=1&hp)
In what may seem a media business version of the Stockholm syndrome, television network executives have fallen in love with a former tormentor: the digital video recorder.
The reason is not simply that more households own DVRs — 33 percent compared with 28 percent at this point in 2008 — helping some marginal shows become hits. It is also that more people seem content to sit through the commercials than networks once thought.
You would then that any media company would think twice before deciding not to release their EPG data.
