Screen capture question for Parhelia or P-series

Hello,

I currently have a G400 Marvel and am considering my next upgrade.

I'm looking for a card that has a composite input and the ability to
take several screen captures in rapid succession without needing
to save and rename each screencap before I can take the next one.
The PC-VCR utility can do this but I'd like to know if this utility
(or a comparable one) is included with the latest generation cards
as it isn't listed on the Matrox website specsheet.
