There ARE a couple others:
- you can turn owned receivers on/off at will; good for guest rooms, traveling receivers, etc.
You CAN'T turn off a leased receiver w/out having to also return it.
- if you decide to cancel DISH & you have shows on your DVR, you CAN continue to watch DVR'd shows - as long as you disco the receiver from the sat signal - & NOT have to return the DVR.
Actually, there seems to be a timer that kills everything if it can't "phone home" after some set period. Varies.
