Can browse, cannot play

[mcn46]

Same problem.
With:
- ONKYO TX-NR808. I can browse but get the message "Cannot Play";
- OPPO 93EU cannot find the server;
-Using Android Bubble UPnP "Resource not found (code 716)";
-Using Android iMediaShare Lite finds the server but: "Unknown error has occurred"

MinimServer works alright with Bubble UPnP on my Android Devices;

I can Browse and Play with no problems using Twonky 6.39 and QNAP NAS TS-112
