"6) In addition to the MCH digital connection, I connected the Oppo via a normal SPDIF port so that the 2 channel DSP processing modes (such as Trifield) could be applied to 2 channel sources... because there is no COMMS connection to the Oppo the G98 can't 'know' the type of source that is incoming over the multi-channel digital... it assumes 5.1 and only offers the multi-channel DSP modes... no big deal since either path is equally good for 2 channel."

I don't know about the BD83 but on the other Oppos you are better off creating a virtual input that uses the L/R input of the multi-channel MHR input for this. The reason being is that on the other Oppos the stock SPDIF output turns off on SACD playback and/or is downsampled for that and other material.
