I'm trialing Mezzmo for Android TV on a 2017 Nvidia Shield device. I'm having odd issues with subtitle behavior.

Note that I have transcoding disabled for the devices, "Stream external subtitles" is the only option selected on the "Subtitles" tab, and I am using the "Conceiva Mezzmo (Android)" device profile.

On the Mezzmo Android TV app, I have subtitles completely disabled (?).

When I play certain movies, subtitles play no matter what. It reminds me of VLC playing subtitles by default, except there is no way in the Mezzmo app (seemingly) to toggle subtitles other than as a global setting (I'd prefer to toggle them on/off while I'm watching a movie, but I can deal with that. It's that it seems there's no way to turn off subtitles. I can turn them off just fine for the same media files in VLC, though, so I know they aren;t forced.

Ideas?

Thanks,
