Random DVR / Commercial remove issue

Hello,
Since the release of commercial skipping feature, I have had 4 instances of somewhere close to the last 12-14 min of the show un-viewable. Watching the recording will be going very smooth, then suddenly the spinning circle pops up, and screen goes black with error message (i wish i could remember exactly but something like) “there was an error in recording your file”. Based on the time stamp, the whole show was recorded or at least a record exists with the full length of time, but nothing you can do will get you past that point or able to fast forward past this. I have not had this issue when we set DVR and do not enable the commercial deletion feature. The errors have occurred on both my Windows PC Plex server, and my Synology 418Play, as well as on the last two versions. Currently using the latest available …666 version. At least two of the occasions occurred on CBS (survivor and Amazing Race). I am OTA with two HDHomerun 2-tuner units. Has anyone else experienced this?
