ok I think this issue can be put on HOLD in my case, it has something to do with permissions, bad owner or group. I started recording a new test-show-schedule and reproduced the error., then changed the recording location and rebooted, and then the same test-show-schedule started working for my test. I see some differences in owner+group in the test-location and the changed-location, so I’ve probably messed up the default recording directory owner+group somehow.
Thanks, please disregard my request.
