I created virtual channels of the TV shows I like to rewatch. They have been working well.
However, today I moved the video files for a show into "Season ##" sub-folders. I then went into the TV show and pruned deleted. Then I deleted and recreated that shows virtual channel. Channels-DVR also scanned and found the show files in the new sub-folders.
Now the virtual channel won't play the episode in the virtual channel. However, it will play that episode when I navigate to the TV show via the Library and select that same episode.
