Ok, I connected the video out (RCA) from the G3 to the Video 4 input and mono sound to L input. I went into the "Input/Output" menu and confirmed that Video 4 is set for input, hence the "green LED". I even changed it to output (red) and back. Strangely, all I get is a black screen when selecting Video 4, instead of the blue screen I normally get when there is no signal. I know it's not the camera or TV because after messing with it for about half an hour I gave up and plugged the G3 directly into the TV and it worked like a charm. Am I doing something wrong or is there a problem with my new 525?
