Roku 3s not showing on 'Play To' List

Just trying the Mezzmo Pro Trial. Roku 3 (3 of them) and Android Tablet all show in the 'Media Devices' on my Windows 10 PC. All devices are 'Allowed'. Allow all new devices is also checked.

All devices see the server and can play movies/music. All are on the same network and 2 of the Roku are wired so network is good.

Tablet (Android 4.2.2 with latest Mezzmo App) does not see any of the Roku. Windows 10 PC does not list any of the Roku but it does show the Android Tablet in the 'Play To' Device box.

I've rebooted all devices and server.

While the Roku App is fine, I really want to use my Android Tablet as the main 'Remote' to push movies/music to my Roku. From everything I've read on the Conceiva website, I should be able to do this.

Am I missing something or does anyone have any suggestions? I would like to get this going before the trial runs out.

Any assistance is appreciated.

Hi Dale,
the Roku Mezzmo App does not operate as a Digital Media Renderer (DMR) and does not implement the AVTransport interface so it will not appear in the Mezzmo Android app's device list. Currently the Roku App is only a Digital Media Player (DMP) so you need to browse the content through the Roku App to play media. We may add support for AVTransport in the future.
