Shawn, thanks.

I finally got to try what you suggested, but it didn't work. If I set the 1070 to DVD 7.1 everything comes out of the surround speakers, nothing from the mains and center. It appears that the 1070 is getting analog input, because sound comes out even if the source is set to optical1, which is not connected. I have tried setting the DVD player to the 2 channel SACD area and tht doesn't work either. The only way I get sound out of all channels is to play the SACD CD area.

Anyone else got a suggestion?
