Cross 3.0 RC video capture device

Hello, I am trying to get an Avermedia Darkcrystal Duo capture card to work with Cross 3.0 RC. The devices show up when I look in the video devices tab but all I get is a black screen. The card says it will work with any Directshow capable 3rd party software.

Anyone have any ideas on how to get this thing to work?
