How can I get my DVM2 to go to black upon stopping when using a contact closure?
Since there is no way to tell the DVM2 to mute video from the discrete control interface, you can make your stop button select a clip that is 1 second's worth of black video and silent audio. If you don't happen to have your own you can download a 1 second black clip with silent audio here: ftp://ftp.alcorn.com/pub/content/NTSCblack.mpg]NTSCblack.mpg

We created them here in the office, so let us know how things go, as we like to gain confidence in the video in customers' hands. The more feedback we get, the better we know whether we can continue to send this to other customers with the same need. Also remember that if you cannot use these clips to assist you, you can encode your own just as easily.
