Since then I have recorded many Free2Air and watched them later.
However in the last month I have found that programs I recorded some time ago don't playback.
Recent recording can be played back without any issues.
The ones I cannot replay either don't start, or the playback progress bar appears for 1~2 seconds, and then disappears.
I don't think the disk space is a problem: 148.95GB has been used of the 1TB installed.
As an example of the age of the problem recordings I cannot replay Episode 1 of the series 'One Lane Bridge' recorded on the 19-06-2021, but I can play Episode 2 recorded 26-06-2021. There are more like this, only of a earlier date.
Technical details of the recorder are.

Is the a problem other Geeks have encountered, and how could it be resolved.
I completed a problem report on the Dish site last week. So far no response.
