As an additional workaround, you can disable subtitles on the server. The AndroidTV client uses the server’s settings, so if you disable subtitles there, they won’t load automatically on the client.

Go to Settings -> Subtitle and set Subtitle mode to None.

I did two separate tests (mp4 container with dvdsub) and they both had the same results. When I leave the subtitle mode to default the subs will load automatically and ATV will request a burn-in and the server will error out causing playback failure. When I set subtitle mode to none, the ATV starts without loading subtitles causing successful playback. ATV is the only non-web-based client I have to test.
