I really don't think there's any immediate danger of them shutting off the DVR functionality if there is still a chance for the entire appellate court to hear the case.
But I will say that this is a HUGE loss for E*. They had already been trying to upgrade people to mpeg4 receivers, so there are a lot of "offending" receivers taken out of circulation. The problem is, though, that they are basically having to pay for all of those receivers that aren't even in peoples' homes anymore! So E* had to put forth the money and effort to switch people out, and are still going to have to pay for "ghost" receivers. That's where this hurts financially.
