I agree with AusTexRocker's theory - I don't want a receiver or a pre/pro to have highest end video processing. Put those chips in the OPPO or other brand player and connect it directly to the display (TV or projector). Best video and best audio chipsets in a receiver or pre/pro serve to make them most expensive. In my opinion, the main function of the pre/pro in the case of the 978 is:
#1: audio SQ - put the best audio chipset in the 978
#2: signal management - switching amongst various front end components with no signal degradation
#2: room correction (if that's high on your list)

If you have a DVD player that contains the very best video AND audio chipsets, then you're buying a pre/pro for preamping signals from components other than your OPPO, switching between components and what else? - room correction? Seems expensive for just those functions.

YMMV
