I have installed the Dell firewire card and it works. Still one or two anomolies: the 2core Win7 computer does not flag up a cam attached to it - my XP immediately asks me what dv edit programme I want to open. My software gives me a preview window and records direct to hard drive, but does not then open that file for editing as on XP, I have to find it on the hard drive and then import it to the software.
The old firewire PCI is a 4 usb to 2 firewire card so it stays since the usb's function. It is a *PCI Express* card and the firewire sockets on it never worked, not even once. So for the first time ever I can use my best cam on the computer 🙂
