Does anyone know if, after the 522 is paused for a long period of time, a screensaver kicks in? I think I've paused it up to 4 mins or so and all I see is the paused image on the screen... I have a rear projection TV and it can be burned if an image is on too long... I used to have an RCA PVR and it went into screensaver mode (The letters RCA would bounce around the screen) after 2 mins... just curious.
