I don't mean to hijack this thread, but I have a question along the same lines.

I am using an OPPO 981 DVD player and have it connected to my Onkyo SR605 by hdmi. I have set the OPPO player's audio output to "raw", which I understand will mean that when a SD DVD has a soundtrack in DTS, the OPPO can transmit the DTS audio codex to the receiver over the hdmi cable.

However, when I play "Master and Commander" and select the DTS soundtrack, the receiver does not display the "DTS" logo, but instead displays a short form for 'multichannel pcm 5.1'.

My questions are: am I getting the soundtrack in the DTS? if not, why not?

Any help would be greatly appreciated.
