I have just purchased 3 DCS-932L'S and installed 3.11 D-ViewCam software.  I have done my best to configure the mainconsole correctly so that my cam's will record on motion based occurances on a weekly schedule of 24 hours a day everyday.  I have a lot of evidence that the system is recording as when I have the console open that there is motion detected and there are 3 folders in my nas unit that has tons of .dat files in them.  My problem comes in when using the playback system.  When I select the search by date/time button and locate the folder that is for a the camera I am interested in playing video for the results never show up!  
any help would be appreciated.
thanks
