Hi Chris, you aren't the first person to have this problem. Be aware that for some, including myself, this problem ultimately lead to a crashed and dead receiver. If you have programming on your DVR and an EHD, back up your programs while you can. Other than that, I don't have a real answer. Watch out for that 3am update, that was the final nail in the coffin for my 722k.
Hey KAB, here is another one. Am I still "pulling the fire alarm"? A little over a week and the complaints are still coming in. We have experienced very similar problems. Maybe my claim might be gaining enough traction to have some investigation by Dish into this matter.
