I see your point but I'm not sure it's accurate. I agree that in 
passthrough mode no processing should happen by the audio card DACs but 
there still may be a driver limitation for a 48kHz card on what source 
signals can be passed?

I've done some more testing and can confirm that I'm seeing 5.1 (DTS / 
DD) and 6.1 (DD-EX / DTS-ES) on my A/V receiver when playing DVDs in 
xine and telling xine to pass the audio output through the optical 
connection on the front of the pundit.

I haven't found any two channel DD 92kHz sources to test with yet 
though. I suppose it would help if I knew the audio specs of DVD-Video
