Hi alol ive just bought a SONY STR-DG510, to connect my ps3 and xbox 360 up for some surround sound! I want to output to my TV through the HDMI socket! The ps3 which is pluggged in to the amp via HDMI works fine, I get a picture on the TV! However the 360 which i have connected to the amp via component, does not seem to output video through the hdmi cable connected to the TV! IS this correct? can it not convert the component signal in to a hdmi signal ?
