After spending time setting up the Yamaha 1400 I cant seem to get OSD (OnScreenDisplay) to show upover a video signal when viewing through Component out of the amp. I have setup all my audio/video equipment through my amp but cant seem to get this to work. S-video works but not through component into my RP. All i get is the standard grey screen with text but isn't overlayed over the video signal. I have checked the manual and set the option for component OSD to 'on' in the menu but still no joy. Can anyone help me?
