Well I had a surround sound dvd player hooked up to the projector. Was watching dvds. But had cqble company come out to install a box so I could watch football on itt, and he said I needed to get a new reciever. So I got this one. I have the component ps3 hook up but there's no where to plug it up to the projector. I've got 2 rga inputs, s video, and yellow video input. Can't plug up the ps3 by itself. I read about buying a anolog to digital converter, but found them backwards. Found vga to hdmi, but need hdmi to vga right?
