No matter the outcome of the lawsuit, the networks will lose more than Dish.
If the courts side with E* and allow them to keep the ptat and auto hop feature, more prime time programming will be viewed because of the ptat feature, however the commercials will be skipped. If the courts side with the networks and E* has to disable ptat, less prime time programming and less commercials will be viewed because not being able to record all prime time programming. Or if auto hop has to be deactivated but keep ptat, people can still skip through the commercials by using ff. E* will probably will tell the networks, if the networks like Dish's ptat feature, its keep ptat and auto hop or nothing at all. And if the courts side with the networks and E* is forced it deactivate all their dvrs, then E* can counter and say the same has to happen with all service providers and their dvrs. At that point, the other service providers will jump on the bandwagon and fight the networks and their dvr shut down.
So the networks can have more prime time shows viewed and have their commercials skipped automatically. Or have their commercials skipped by using ff. Or have a large lawsuit by all service providers because they are being forced to deactivate their dvrs.
