Apple TV cannot display older purchased videos
My wife and I are going back to the beginning of a TV series. The episodes were purchased starting on 2015 via iTunes. The files are still there, but if I try to mirror to our TV, it says the video cannot be played on that TV. It used to play purchased videos just fine.
What is the problem with older vids that (I assume) Apple TV blocks their display?
Thanks in advance.
