I use the Dish Hopper. Occasionally in the past I have noticed that the On Demand function on my DVR has quit working for all the various choices. When I go to an On Demand choice (either through the On Demand choice on the Home Menu or through the individual On Demand channels - like National Geographic, Comedy, etc) and I click on the rent button, nothing happens. On some channel choices, like EPIX, it goes through a few additional steps - "rent HD" or "rent SD" - "You have chosen to rent...blah blah...yes/no" but clicking button still does nothing.
Any suggestions? The internet connection shows as functioning (green bars all the way).
