I recently purchased a Shield TV and got connected it to my Plex Media Server, but I found that some movies are not able to Direct Play, but fall back to Direct Stream instead. When direct streaming the movies do not display the PGS subtitle track, and my receiver displays "LPCM 5.1" instead of the expected "DTS-HD Master Audio 5.1". I have audio passthrough enabled, Direct Play set to force, and quality set to Original.
I enabled network logging and played Lorax (which worked fine) and Lego Movie (which did not).
Attached are the XML files for a few movies I tested:
The Lorax: direct played
Juno: direct played
The Lego Movie: direct play failed, fell back to direct stream
Big Hero 6: direct play failed, fell back to direct stream
I have also attached the relevant portion of the Plex Media Server log for when I had network logging enabled.
Thanks.
