Kona capture cards with Jitter?

Hi all,

Despite my earlier missive about BlackMagic cards, the powers that be
(i.e. the people purchasing the hardware) decided to go with a Kona HD
card instead of a BlackMagic solution.

Does anyone have any experience with these cards and Jitter?

My cursory searching seems to indicate yes. Did it work well? Any drawbacks?

Thanks again,
