HD video capture

Hi,

I have got hold of an Aver HD capture card with an HDMI interface and I was hoping to use it to capture into VVVV. The Video in node sees the Aver capture card on the input select pin but I can not seem to get a signal. Has anyone used one of these cards and had any success with it? If these cards are no good could anyone recommend a better one?

Thanks in advance,
