I have a 508 and a 501 and when i turn on the TV in the morning I get "snow", then I press channel up and the receivers come back on. THen on the bottom of the screen it says "disc is spinning up". The receivers are left on all night. Is this suppose to be a screen saver type function or is it a bug in the receiver that Dish is working on? If anyone has any insider info I would appreciate it.
