I searched the forum, and did not see this issue. My apologies if this is a known issue.
There are several series in Primetime Anytime that I save in order to watch later. Two series, APB, and This is Us were saved and appeared in my DVR. I removed them from PTAT but they still show in the DVR as they always have. A few days later, I noticed that one of the episodes of This is Us was gone. I searched for it in the Deleted Items (now called "Trash") and it was not there. I searched using the Search feature, and it was not to be found. I manually went to On-Demand , found it under the NBC tab, and downloaded it to watch that way. Two days later, it was back in my DVR. Something similar happened with the other recording.
My issues are two-fold:
1) What is happening for the recording to be hidden? It seems since it comes back and never appeared in Trash it was never deleted.
2) Why does a search not show items available On-Demand as it had in the past.
