It also shows Bitstream as an option on the HDMI audio set up. When I change it to Bitstream it then lets the 705 do the work. Instead of multichannel on the 705 display, it shows what ever the audio track is selected from the DVD.
Really, does it show PCM and DolbyTrueHD? I have an 805 and has not done that -- I will try it when I get home.
