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.

I also have a Roku Ultra 4800X to test with.

I will be home in a couple hours and will report back on both the Roku and CCwGTV 4K with DVDSUBs.
