Is there a sticky post or white paper here somewhere that categorizes updates to DISH devices in terms of type, and how and when those are delivered? We seem to get some kind of updates on a regular basis, usually late at night. We had thought that these were the only updates available, but I'm seeing posts here that suggest that there are major software updates for Hoppers and Joeys that are only downloaded and installed on user demand. Is that correct? If so, I'm like to find instructions on how to identify and download those updates, as well as what precautions to take to be able to remove one should it prove to have undesirable effects. Thanks!
