I have a G5 with an Active Silicon Frame capture card (LFG4-MM-PE1) build in
I grap 3 chanals composite video and show them with the Catalyst and a Matrox Triblehead analog in realtime 2400x600p.
The problem I have, is that the signal is not running smoothly.
Then a turn off the preview on screen one, they are running more smoothly, but not good.
It looks like the G5 has much more kraft to run it, Catalyst is only use 17% proc. kraft

Can some one help me with the problem. I think it must be a setup thing in the Catalyst

Best Regards
Claes
