However it's slow to update the list when you have alot of movies + it takes extra long time to start movie playback when it is set to transcode insted of direct play.
This thread has confused me about Direct Play. I thought that Plex will automatically Direct Play any MP4/M4V with an AAC audio file and the fast start atom enabled. So why is a Force Direct Play option needed? How can you force direct play if the file doesn’t meet these criteria? MKVs are direct streamed or transcoded (depending on their audio), AVIs are always transcoded, and MP4s are direct played (if optimized), or transcoded.
