I can confirm this is an issue with the latest firmware:
Agent Version: 2.0.19-b80
Current NVR Firmware Version : v2.02.00
Firmware Date : Sep 16 2015
Current NVR Device Pack : v2.10.02
In the previous version (prior to the new "stainless" interface), when selecting video to view through the calendar, you would have the red continuous recording bars, but also blue highlights where there were motion detection events.
In the current version, it all shows as the red continuous recording bar, regardless of whether or not motion detection events are interspersed. They're also not reflected in the Event List on the Playback page.
The motion detection events are logged and can be viewed in the log panel of the Live View, and the motion detection icon flashes in the OSD when playing back recorded video, so the DNR-202L is definitely receiving and logging the motion detection events.
(Unrelated, but the bug still exists where recorded video exported from my DCS-932L has audio that plays at half-speed unless I fiddle with the header in a hex editor. Video exported from recordings of my DCS-2132L is fine.)
