I leave my 211 on 24 hours a day because it's in a public display area. I did the same thing with the 811 it replaced. Even with the "unattended" actions turned off, the screen saver pops up every day (I think in the wee hours of the morning when the guide refreshes). After discussiong this with my Dish Technician I'm wondering if this is actually an unnecessary bug brought over from the DVR versions of the new MPEG4 receivers. I mean, I know the screen saver comes on on those models to protect the internal hard drive, but why do you need a screen saver in a non DVR model?
