My question is this does the de-coded HD audio signal come out from the coaxial / optical or analog outputs or only hdmi ?Just to set this straight, the new lossless surround codecs CAN'T be transmitted via coax or Toslink, ever, period. The SP/DIF connection (coax or Toslink) can't handle the bandwidth requirements of a lossless 7.1 channel datastream. That's why the SP/DIF output of an HD DVD or Blu-ray player outputs a downconvert in DTS format of the hi-rez soundtrack.
Lossless 7.1 ch. digital datastreams from the HD DVD and Blu-ray codecs (and SACD surround, for that matter) require HDMI. They need those extra conductors to transmit all those extra channels without lossy compression.
