looks supported,though , might entirely wrong, otherwise don't think you'd have gotten output. looks pointing @ wrong v4l device, if have more 1 video capture device installed. try /dev/video1 or /dev/video2. otherwise.
predict i'd have similar problem when webcam, have tv tuner card installed well(which shows /dev/video0 on computer, btw).
