I would like to second this feature. It's my fault for buying the NVR without verifying that this feature was there, but for some reason it seemed like a feature that should be on all security systems. I guess I just got spoiled by Blue Iris.

My use case is record 24/7 the front door, when motion detection goes off I have it e-mail me and this works. But a single screen shot simple isn't that useful. It would be easier if the PC client had a skip to next event button and would play from there.
