    An audio/video switcher probably won't do the bandwidth on the audio portion (e.g. red and white). What are you trying to hook-up (source devices - e.g. DVD, VCR) to what TV and what kind of inputs do you have on the TV and audio rec'r?

    So that I understand what you have hooked up - you have an A/V switcher with an output to your projector and it has only 2 component inputs and you have 4 devices that are tied into the A/V switcher? The video inputs of the switcher are the what is getting routed to the projector and it is probable that the projector inputs may not upconvert a composite input to the hd15 output? You may have to hook a composite from the switcher to the projector (or 'S' from some devices to the swithcer and then 'S' from the switcher to the projector). What type of swticher is it and what are it's inputs and outputs?

    If you have the GREEN connector from the component video plugged into the YELLOW connector on the switcher, attached to the GREEN component input, you should get a picture, if a crappy black-and-white one. The GREEN connector actually carries the LUMINANCE signal, equivalent in many of its characteristics to a composite video signal; colour-difference signals R-Y/B-Y are on the RED and BLUE connectors. Since SYNC is packaged with LUMINANCE, and the SYNC frequency of progressive-scan NTSC is 31.5 kHz, above the audio band, I doubt that an audio connector would pass enough undistorted SYNC for any input device to be able to interpret the signal. You do want to make sure that your projector is actually set up to accept a progressive-scan signal.
    In any case, though, this is not an acceptable device for use as a video switcher, because it does not have proper bandwidth or matched impedance. Get somethng else; you can buy a cheap component switcher at Radio Shack.
