The court ordered the DVRs on the list to have "the DVR functions" disabled. It has two meanings:
1) Any patent lawyer will tell you "the DVR functions" stated in the order only refers to the DVR functions operated by the old infringing software, so if such DVR functions under the old software are gone, the order is obeyed. DISH did just that, they removed the DVR functions by the old software, and replaced them with the currect DVR functions under the new software. The judge will rule in favor of DISH because this is how the standards govern the current contempt decision.
2) The court order does not say DISH may not continue to use those DVRs, only the DVR functions under the old software must be removed, once that is done, the DVRS can be used any way they want, as long as they no longer infringe on the Tivo patent. So if for whatever the reason DISH decides to actually disable the DVR functions, yet not replace them with another set of DVR functions, it will be perfectly fine for them to update the software for those receivers so they continue to work as if there is no harddrives in them.
What I am saying is, even if the current DVRs may not be used at all once the hard drives are dead, because the way the current software is designed (which is not true according to the evidence provided by many users), it will still be easy to update the software so the receivers will continue to function as if they did not have hard drives.
Of course if those DVRs become non-DVRs, you can be sure you will not pay the DVR fees, and most likely DISH will offer you some kind of monthly discounts until they can replace your DVRs with the newer models, for free, so you can again use the DVR functions.
But rest assured, you will be able to continue to use your DVRs, don't listen to all those Tivo folks, they are everywhere trying to spread misinformation. Some of them are Tivo investors we already know, and you will just have to decide how much you can trust what they want to tell you.
