This problem has been reported by others but just checking to see if anyone found a fix. When watching a video using plexconnect it will often stop after a variable amount of time and go into infinite buffering. You then can't play anyhthing even through the standard home sharing method. Only an ATV reboot fixes it. Doesn't happen if you play video just through home sharing. On latest plex, plex connect, Atv3. Tried a restore through iTunes. It started about a few months ago. It now makes plex much less useful to me if I have to restart ATV all the time.
