Gerald,
This configuration might work (no promise).
Right click on the G91, and select properties. On the Audio tab, under Aux MHR select NO. This should allow you to pass DD/DTS streams to the scaler.
Here's an image that shows what the Audio Properties Page should look like:

Then build a User Defined source for the scaler with the appropriate Audio Inputs/Outputs for the Scaler. Connect AUX out to a digital input on the Scaler, and connect the digital out on the scaler to a digital in on the G91. Connect the rest of your digital audio inputs to the scaler too
Here's an image of that connection diagram. Note that I only have one input and output on the scaler at this time. KISS for illustrative purposes, right?

The only negative of this is that you won't be able to use the MHR to control all of your components, but I'm guessing you aren't anyway
