S-Video In with Pinnacle Dazzle

Hello -

Has anyone successfully gotten S-Video in to the beagleboard through a Pinnacle Dazzle (S-Video to USB)? I am running ubuntu and have downloaded the v4l driver. The device is recognized and is set up at /dev/video0, but when I try to stream the video from the camera, no video is output to the screen (through the HDMI to DVI-D).

Any advice?
