Changing HR20-700 screen saver time?

[darthemma]

I have two HR20-700 dvrs and one of them is connected to a new plasma. When I pause the dvr while watching a program with black bars, it takes several minutes for the screen saver to kick in on the dvr and I notice slight burn in of the bars. It goes away shortly after returning to hd programming, but I don't want this to damage my new plasma over time.

Is there a way to shorten the length of time it takes for the screen saver to kick in on the dvr when I pause the hr20? I haven't found this in any of the menus.

Thanks.
