Play to, dlna

[Jman4000]

I used the plug in and it’s installed. Does the plug in not allow the “play using option”? I see it showing up now however upon sending it to my Blu-ray player (which it does see) it doesn’t play on the Blu-ray player. Can that work with this setup? I’d like to play try 4k voids through it (oppo 203). Or would I have to create a different setup?

Thanks in advance
