Android TV doesn't like DVDSUB subtitles?

I ripped a DVD then encoded to HEVC in MP4 wrapper and included the subtitles.  ATV (on my Shield) won't display the subtitles during play.  Web app and std Android app does.  When I do the same with recorded TV ATV will display the subtitles.  Are subtitles from a DVD not working a known issue with ATV?

I assume the reason Emby had to transcode is only because of the subtitles? Never would have I thought but I don't know much about subtitles.

Hi, what did the stats feature list as the transcoding reason?

FFmpeg log says "TranscodeReasons=SubtitleCodecNotSupported".  What about the issue?
