I have connected a SCART - RCA composite cable and the capture window once showed the image, sound stopped and started and noticed the mouse sluggish.
Also tried a SCART - RCA L/R audio and SVIDEO cable and was not better.
The capture card I have is the following running on Windows 7 x64

I tried a little program called AM Capture and can get the picture up in it but no audio, picture is ok though but minor fuzziness around the edges of people etc.
So, wrong cable? software don't support the card? would like to get this working
