Playback failed errors

Do you use any sort of screen sharing or remote access setup? If you can provide remote access I can poke around and see if something obvious is wrong.

Yes, I do. What is the best way to set up for a remote session?

Very weird solution; I received a message on my Mac this morning that advised that ChannelsDVR wanted access to the drive in question, I granted the access and now all is well. I tested several tv show and movie recordings. Thanks for trying to figure out with me on this one! You guys are great.

Huh that's strange.

What version of macOS are you using?
