If we see how firewire video capture card able to capture dv cameras at full screen, mostly without dropping frame (if you have enough RAM and cpu speed), you know the future is in the firewire ----- Original Message ----- From: "david stock" <email@example.com> To: <firstname.lastname@example.org> Sent: 21 February, 2000 04:26 Subject: Re: 1600 firewire > on 2/19/00 7:19 PM, Gary L.
