Fox asks appeals court to stop Dish's ad-skipping DVR, right now

Fox Broadcasting, having lost a key court ruling last month, is more eager than ever to kick Dish Network's new ad-skipping Hopper DVR off the market.

Last month, a federal judge found that Dish's DVRs probably don't break copyright law, ruling that the Hoppers can stay on the market and operate normally while Fox proceeds with its lawsuit. Fox is arguing that it can't wait, and it says that Dish's product has the potential to do serious damage to various aspects of the ad-supported TV business. As promised, it appealed the lower court decision and has now filed its opening brief at the US Court of Appeals for the 9th Circuit. The various affiliates of the Fox media empire originally filed the lawsuit back in May.
