@Doktor_Marc - disabling direct play actually forces a direct stream, which works well as a workaround (not much load on the server). The issue seems to be how the ATV perceives the movie file container.
@oryan_dunn - leaving quality settings as “max” or whatever is suitable for your network should be fine. Setting “Allow Direct Play” to Off will allow that content to play, which under the hood makes the ATV direct stream the content.
@SuperMatt - Will try that, but most external users to my network will forget and want a static solution or workaround.
@hallofjames - Try disabling direct play as a workaround and let us know your results. The resulting direct stream should be no issue for your server and is nowhere near as intensive as transcoding.
@pr0j3kt - Please let us know your results, curious if the workaround is successful for you as well. Just this past weekend I had yet another friend with ATV4K running the latest Plex app that had the same symptom originally, but most recently had to uninstall/reinstall the Plex app, then link again to see my library! Once linked, disabling direct play was the only way to reliably watch content. All his other Roku and FireTV devices had no issue with direct play.
