Is there a way to program the 811 to "sleep" after 30 minutes? I used to set the TV to sleep after 30 minutes, leaving the Dish on. Then the Dish folks told me to turn the 811 off at night to get the updates -- I did. But if I have to turn the 811 off, the sleep function on the TV becomes useless. Did I miss a page in the manual -- shouldn't this be easy to coordinate?
