I have a surround sound amplifier with surround sound speakers. No HDMI inputs or outputs on the amp. Limited to RCA or s video. My direct tv box only has a video, hdmi, usb, or Digital audio options. Lastly I have a projector with hdmi inputs, s video inputs, and component inputs. I want to take the audio and video from the direct tv box, have the audio come through the amplifier, and the video go to the projector. Is this possible??
