Argh! Well on that bitstream part - once again having what the HD DVD guys call "helicopter" noise when I just played one of my HD DVD discs (the aquarium screen saver type of movie). The same thing happened with my Tosh A35 HD player as well. It seems to be an HDMI handshaking problem, and some have mentioned Onkyo is bad with this, and the Denon works fine. But it only happens with HD DVD movied using DD+ or DD THD = NOT when playing BD movies. I have a very early Onkyo 805, am hoping that maybe the newer 806 has this fixed, or maybe I should go try a Denon (2309 or 889).
