I just got a brand new 211k and I notice a difference from my older 211k. When I hold down the arrows to scroll the guide on the new receiver -- either right or down it only scrolls a bit and stops. In order to continue to scroll, I have to release the button and start again. With my older 211K, I can hold the button down and it keeps moving until it hits the end. Is this a bug ? Both receivers are running the same software version . I have tried unplug, reset, etc. Also notice that the scroll speed is slower than my 722k ( probably slower processor) Looking for suggestions.
