Unlikely...

BTW, this is what the Canopus Raptor did so well on "slow"

computers: with its hardware overlay, you could run a

full-frame-rate, full resolution computer-monitor preview

window on the computer plus run a TV at the same time

(with a camera, DV-VCR, or converter box added to serve

as a converter). This is partly why I continue to use this

discontinued card - and the codec is both high-quality and

fast-rendering, giving me a speed advantage compared with

the MS codec equivalent to having a CPU of about double

the speed...
