I may be wrong, but I beleve that HDMI only delivers the audio signal in that format and you have to use either an optical or digital out cable to utilize the dolby digital signal of the receiver. I not 100% sure on this though.
Do you have the Dynamic Range Control option set to on? For DD to output, the decoder has to implement Dynamic Range Control.

HDMI 1.3 can carry any multi-channel digital audio format. DD, DD+, DTS, DTS-HD, and DolbTrueHD.
