DTS HD and the other multichannel audio formats can ONLY be transmitted from the player in the analog domain or via HDMI 1.3. To the best of my knowledge, no 1.3 compatible pre/pro or receivers ae out though they are rapidly on their way.
So to answer your question, yes, they can be done in the player, but would then be sent via analog outs, ideally they would go to be decoded by the pre/pro but HDMI seems to have a real jitter issue so we'll see how this all settles out.
