Apple TV app not playing ripped MP4s from external drive
I have several DVDs which I purchased that I ripped to an MP4 so I could play them through iTunes (old) or now Apple TV app on my Mac and my Apple TV 4K. This all worked last Christmas which is when I use this most for Christmas movies. Now with a new MacBook Pro M4 connected to my external drive with my media library, the movies do not play. I have verified: 1) Media Sharing is turned on in MacOS settings; 2) Apple TV Settings/Files points to the iTunes folder on my external drive. I can see the movies but none play. If I click on the 3 dots and Get Info, the File tab says under location: "Kent McPherson's Library". I remember this used to point to the specific MP4 file itself. What am I missing?
MacBook Pro 14″, macOS 26.1
