Two days in a row my Plex DVR has refused to record the same show. I have 6 tuners on 3 HDHomeRun devices. It failed with the following error yesterday and today. Yesterday it went on to record 3 other shows later in the evening, two of them on the same tuner that failed here. I’m running on Windows 10 Pro, Plex Server version 1.13.9.5456. This is the show my wife watches when she gets home for work, so, you know, it’s important
