I'm about to start using my PC as my AV source. So, the sound is going optically to my amp (no problem there) but I have a number of visuals options. I've just bought a projector with S-video inputs which also takes 480i. I can run s-video or component cable from my video card (Radeon 8500) to that port no problem. However, I hear that the VGA input on the projector can also be used for a 480p signal (something to do with RGBHV?). Question is, can my PC generate this signal? Can it come direct from the VGA out? or do I need a specialsed dvd player or video card? This is the last stage of getting my HT together, everthing else is sorted so any advice would be very welcome, Cheers.
