Well, I can confirm that the problem is not with the DNR-202L device. The problem is with the HDD Viewer Software.
As a temporary solution, I have manually changed all the dates on all my DNR-202L devices to 2019. This enables me to view the recordings in HDD Viewer, even though the dates are off by one day since we are in 2020. But better than nothing at this stage.
I'm still hoping for a speedy solution to this by D-Link as this is ridiculous that we are expected to use dated software with such a silly bug. However, I am already pricing up another system by either Swann or Reolink to replace this non-supported D-Link system if a solution is not found in regards to an update and proper working HDD Viewer software.
