Hmmm...didn't check, but the 1600 does have HDMI so that is a good thing. Yes, need to know what the display is and if it has HDMI or DVI also.
I think that is a mistake - if you put in a regular DVD with a 6.1 track, it will play back correctly. It is talking about LPCM 7.1, which you do need HDMI for.
HDMI on the 1600 is only 1.1 so it will not work for SACD, AFAIK. Does 1.1 support HDCP?
