I used an iMac (27-inch, Mid 2011) to shared videos，then i used infuse pro to load this video. It seems fine when start playing the video, but an error occurred when loading the content. I had updated the latest version 4.0.2 on my Apple TV 4. Use smb to connect. I tried several times but it will stop at 4-7 mins when playing the videos.Wish some can give me some suggestion for my settings.
PS: It is strange when I see the smbd process stop upload. I don’t know why.
My device: iMac (27-inch, Mid 2011) ,Airport Extreme AC
Update: Thanks for pederl.1988’s sugguestion. I have tried connect via FTP, everything goes fine. But I am using OS X Server 5.0 to set up FTP server. Hope it will be useful for other user.
