Hello,
the record buttons are crossed, if the recording is still running and not if recording is not possible.
Have you started the recording before?
Please remove the cameras from the program and add them again.
Are the buttons crossed immediately after you have added the camera?
Or after which action they are crossed?
To be sure, that the DirectShow filters are correct registered please re-register them:
