The reason I don't keep the receiver off is because my mom who is almost 90 years old is illiterate, she only knows how to turn on and off the tv, doesn't know how to change channels, or use the replay stuff so it's easier keeping the box on and then if she turns the tv on and it's showing some show as it's always tuned to the same channel, I can always rewind using the buffer which is not possible if the box is on standby. Standby is only useful if you were recording everything already, otherwise you would not be able to go back in the buffer.
