Found this older thread. Would love a definitive answer. I find JRiver to work really well as a DLNA server with a DLNA rendered (I currently use the PS Audio bridge in my direct stream DAC)...super reliable. Does the BDP work as a renderer with JRiver as the server but playing music off the internal BDP hard drive . I’m guessing yes. Anyone using the BDP this way?
Just to make it clear, I would have JRiver installed on another computer, it would just work as a DLNA server. Ultimately, I anticipate a small nuc like machine on my network, always on and running just JRiver.
