There are some receivers and pre/pros that offer OSD (On Screen Display) via component outs. It's rare though. Even rarer is to have the OSD info overlayed on top of a component video signal. I'm not sure but I think the Meridian 861 can overlay OSD on its component video outs. My MC-12 has OSD on component out, but against a blue screen and not overlayed on top of the video signal (which it does on composite & s-video outs). Even the upcoming $30,000 Mark Levinson No.40 processor doesn't do OSD overlays on the component outs; the info is displayed against a black screen.
The reason for this, from what I've read, is that it is difficult to synchronize video text & graphics to all 3 "channels" of video (which, let's face it, is what a component signal is). It's probably not cost effective for most companies to offer it as a featue.
