Processing from Digital to Analog at the player or at the amp is easy when the player has analog outs which makes the decision possible. Then just choose the unit with the codex you want. I like the Oppo since it has analog output. My Panasonic BD 80 also has analog out, so, I let it process. Of course, for me, this works out since I'm satisfied with 5.1 which is what I've got with my Sony TA-P9000ES preamp which BTW has no digital processing what so ever.
