Does Roamio and Mini have screensaver?

I am this close to purchasing a Roamio and mini to replace our DirecTV setup. I'm pretty nervous about doing so, as I've been with DirecTV since the original DirecTivos.



One thing I just thought of - does the Roamio and Mini have screensavers? How soon do they kick on? Is this configurable?



Having three plasmas, it would be a dealbreaker if there were no screensavers.



TIA!
