This has been going on for some time, after I record something I cannot go to the DVR schedule and play titles from there (Plex server on Mac mini, latest version, with latest version of player on three Nvidia shield on my network). I go to the DVR schedule, highlight the title I want to play, ■■■■ on the title to play it and nothing happens - title does not play, and no error message is displayed.
The only way I can play a recorded title is to find it in TV shows or Movies and play it from there.
It used to work years ago, then it stopped working for more then a year, then it started working again for about a year, and stopped working again about two years ago.
Any ideas what is causing this and how to fix it?
