Dish Network shocked us just a couple of weeks ago by upgrading its new Hopper DVRs with "Auto Hop" ad skipping that targeted prime time programming on broadcast TV captured via its PrimeTime Anytime feature, and predictably, the networks aren't happy. After several executives took shots at the service during upfronts for the new fall programming in the past few weeks, Fox has filed suit in US District Court, while Dish Network responded with its own request for a court order specifying that it does not infringe on the TV network's copyrights.
