Jerry, any 44.1 or 48 kHz signal sent to an 8k or 7k gets upsampled. So yes, DD and DTS will be upsampled before you hear it.

I would really like to see the #s on the 7k sales. What I am looking for are how many 7ks sales are going to be used as surrounds in an 8k system. [Linked Image from softronix.com]

Did I mention the silver 800 and 861 on display at Cedia? I have them on video, I just need to grab the stills from the video stream.
