While that would be nice, in my case I don't expect the set to reencode 
DolbyHD to DTS or any such thing.  What I would expect would be that the 
set to act as a pass through at the very least.  What I am seeing 
currently with mine is exactly what it in the manual:  If the audio is 
from a digital source (HDMI in this case), it only sends out 2 channel, 
even if the original stream is DTS or AC3, which the optical has the 
bandwidth for.
