I just experienced this today.
I have a lot of videos on my 6TB drive.
I added a folder and 1 media file (MKV).
I connected it to my media player and tried to play it.
Then it showed an error message -
“There is no media available for playback.”
Structure for the particular folder in question is –
Videos \ Current (T-Z) \ MovieName \ Season 1 \ Movie.mkv
Is there a maximum number of readable directories or files with the media player?
Under normal circumstances, if I click the “MovieName” folder it would just go in and show the contents.
Note - no network or cloud involved – direct connection only.
