I have both Plex and ChannelsDVR installed on my server. They run as Docker containers. I was playing around with Plex and wanted to see if I could see the Channels DVR library in Plex (just one show - Jeopardy!), so I added the ChannelsDVR > TV folder as a library in Plex. It worked and I could see the show in Plex. However, all of the recorded episodes disappeared from Channels. I confirmed the recorded episode files are still there in the file system. Additionally, the episodes were viewable in Plex.
I removed the library from Plex but the recorded episodes still don't show up in Channels. I double checked and the episodes are still in the TV folder of the ChannelsDVR folder. Since the issue occurred, Channels recorded a new episode of the show and it does show up in the Channels DVR library. Is there a way to "rescan" the DVR library so it picks back up the missing recorded episodes? I'm not sure what Plex did that caused the episodes to go missing in Channels.
