Having a few issues with plex connect and atv3 rebooting when playing certain movies. Any idea where to start me debugging this problem?
I would suggest looking at the mediainfo of a working movie, and a non-working one (preferrably one that works in the ATV4 but not in the ATV3).
I just set plexconnect to always transcode and it worked!
Likely a DD or DTS audio movie with 1080p resolution or higher.
