I meant what speakers were you going to connect to the receiver.
Also, disregard what the users above said about optical. I have mine connected through SPDIF and I get DTS, DD, etc.
Dolby Digital is not the same as Dolby True HD and DTS is not the same as DTS-HD, it's not possible to play Dolby True HD or DTS HD via optical, or coaxial, only via HDMI
