Cannot help on this because don't have the mentioned DVR card.

If you have the hardware, you can debug with sourced of the framework, 
investigate the issue and maybe fix it.

OK, maybe will do something for the next release. I just found my old USB frame 
grabber, which is obviously not the same as your card, but has similar issue. 
There is way to solve it ...

1) Added VideoCaptureDevice.DisplayCrossbarPropertyPage() method, which allows 
to display crossbar configuration page while video device is running. This 
property page allows to select video input of capture card.
2) Added VideoCaptureDevice.CheckIfCrossbarAvailable() method, which allows to 
check if the video device provide crossbar and its configuration.
3) Added VideoCaptureDevice.AvailableCrossbarVideoInputs property, which lists 
available video inputs of the capture card. This can be used to select video 
input to use before running video device using your own UI.
4) Added VideoCaptureDevice.CrossbarVideoInput property, which allows setting 
video input to use by the video device.

The fix was committed in revision 1661-1663. Will be released in version 2.2.4.
