If you're running the DVD player from its progressive scan output, which I assume you are into the Mits, you might get off cheap with the Denon DVD player as it is one of the only less-expensive players(around $500) that uses the Faroudja/Sage DCDi chip that is normally only found in much, much more expensive units. In terms of surround sound it probably will depend more on the pre/pro(and the digital cable) you're using than on the Denon, which probably does a fine job passing the digital signal. Best of luck.
