I agree, I would look at the MSB Universal Transport. I think it has Meridian written all over it. Remove MSB's proprietary connection and add Meridian's, and your off to the races. MSB used the Oppo video, while sizeable reworking the audio portion.

I also see an opportunity to reuse the 808 chassis's. Why can't these accept ID40-ID41 cards. These disk spinners have been crushed in the aftermarket.
