This is a problem for me - an a small mystery.
I can play my NAS videofiles seamlessly with iPad, using Infuse.
But with ATV I can actually see my files (both UPnP and SMB) but I am not able to start them.
When I click, they just go back to normal position after 1-2 sec.
What is wrong?
I have tried to connect ATV with ethernet or wifi, the problem remains.
ATV 4K 32 GB
