Same thing happened with both my HR20-700's. My playlists showed statements that said I had no recorded shows (or something of that nature}. After throwing a major snit fit, I did menu resets on both units, pulling the plug at the black screen, and after they rebooted, everything was back to normal. One other thing I did was unplug both eSATA drives. After a minute or so, I repowered the eSATA's then the HR20's. For all I know, this was not necessary, but I did it anyway.
