On a different topic - one other thing that was strange when messing with the receiver - the bass on the vistas didnt sound that great to me - so I figured it was just the speakers not going very low - I was playing a blu-ray concert via HDMI. For the fun of it I plugged in my Ipod via regular analog RCA and the speakers actually sounded much better to me - bass response was significantly improved!. Is this another settings issue I am clueless about, or is HDMI not all its cracked up to be? Thanks!!!!!!!!!!
