Nvidia Geforce 6600GT 256DDR3 Vivo! What capture chip? What best driver?

I also just got this card and on nvidia site downloaded the latest wdm drivers. It captures with max resolution of 720X576. The image is not very sharp (blurry) and there is no control of sharpness in the driver.

I was wondering if there is any alternative driver for this were you can tweak the quality like the one for bt87x?

anyone experienced with this hardware please advise me on way to get best out of this card.
