Reciever won't play back shows I recorded on-demand

Over the last year, I have seen several changes to how on-demand works for me. It started out good, then did not work at all, and currently will not allow me to watch recorded shows. I suspect this may be something to do with system updates. Here is an overview.

...We have a satellite internet connection with another provider, and it is not the fastest service. We used to have Dish satellite TV, but signed up for DirectTV at the end of 2019, and viewing DirectTV shows on-demand has always been slow and glitchy. But I was pleased to discover that I could record on-demand content to watch later, it would download slowly, and I could watch it the next day with no glitches. I was able to download and watch all the past seasons of Westworld from HBO and I was very happy.

Sometime in mid-spring 2020, downloads stopped working. Shows would fail to record, or they would give me a recording with a run time of "0" minutes. After a while I quit trying. I found that I was still able to record live TV and movies on the air so that is what I did.

Recently, I tried again, after I missed recording several episodes of Resident Alien, on SYFY. I was very pleased to see that they appeared to record: The episodes show in my list of recordings; they have a datestamp (eg. Sun 2:29 AM) and a duration, 44 minutes. I also know that the data was downloaded though our satellite internet service, since my attempts used up gigabytes of our data allowance.

BUT, when I select one of these recordings and attempt to play it, the system acts as if it is trying to do on-demand instead of playing a recording.

When I go to one of these recordings and press Select to play a recorded episode, first it gives me a progress bar with the message "Please wait..."

Then it goes to "927 - The content you want to watch is unavailable now. We're addressing the issue, so be sure to try again later."

Trying again later does not help.

In contrast, I am still able to play episodes of Westworld recorded way back in April 2020.

WHY should content that I have successfully downloaded, and paid for, be locked off so I cannot access it. This is very frustrating. Hours and hours of recorded content is sitting on my recorder but cannot be viewed. 

My internet access is good enough that I can watch youtube with only occasional pauses. It is more than good enough for the DirectTV box to perform whatever handshake it might need to verify I am allowed access to a recorded program. Clearly something is wrong, either it is ignoring the recording and trying to stream, or it is getting hung up on something.
