But i can capture the SDI from a Blackmagic Extreme, so using that i can

Capture PPT powerPonit presentations, or other from another computer source, using the DVI output from that computer, converting to SDI,
DVI - SDI thru the Matrox, and then have that captured right ???
Any guess in how will be the resolution of the computer captured, since the Balckmagic understands up to 1080, i belive i can get a much better result than transforming the powerpoint computer output in Video.

And then that problaby works with Catalyst thru Balckmagic right ?
