You need an SMB server on Windows, but that has been built-in for a long time. It is normal network sharing.
Make sure you report your results to OPPO.
I believe i have found a new bug that existed in the official FW as well as the new beta FW. I am using HDMI_1 output to my Anthem D2v then to Darblet to the TV(Pioneer Elite Kuro).
When i set my HDMI_2 output video bit settings to 30-bits or 30-bits(dithered) in the 105, Audio is MUTED on HDMI_1 output of the Oppo but video is not. When i change the bit depth to 36-bit or 24-bit, then i get audio back on HDMI_1. Now, i realize both HDMI outputs are active simultaneously but was suprised to have HDMI_1 audio muted by HDMI_2 bit settings.
Can anyone try to verify this phenomenon? I don't think its my Anthem AVR that is the problem...
