EchoStar continued to lose ground against its detractors Monday as first a federal judge delayed its countersuit against TiVo Inc., which already has won a patent-infringement suit against EchoStar (which produces digital video recorders for its DISH satellite service). Then, later in the day, EchoStar said that it had agreed to pay $100 million to NBC, CBS and ABC affiliates to settle a copyright suit resulting from EchoStar's providing the signals from distant stations to some of its rural customers. Taking itself out of the settlement, however, was the Fox network, a corporate sibling of EchoStar's rival, DirecTV.
