There isn't any buzzing at all: not from the electronics (ie. ground loop), not from the speakers (ie. distortion) during audio, not when on mute or when dialog is low and volume is high.
There are two settings under advance video for noise reduction but I don't see any difference when applied. Video Noise Reduction (Video NR) and MPEG NR. I tested both with SD signals from cable and DVD, couldn't really see a difference. I think its scaler is pretty good. I have a 59avi and I prefer to let the TV scale my DVDs. Last night I fed it 480i via HDMI and watched part of "The Return of the King". Seeing how great the picture was made less anxious to upgrade to Bluray.
