FireWire problem #1 solved
The shop still hadn't got my iPod back from Apple when I called in on Saturday, but the guy said that Apple tend to replace rather than repair, so he gave me a brand new iPod to replace mine. When we got home, I plugged it straight into the IEEE1394 port (on the powered Belkin card), and XP recognised it straight away and installed the drivers for it.
So, now all I have to do is wait for the camcorder to be suitably repaired (or replaced) and I'll be back on course to do something with all of that video of the kids
Can you tell I'm happy?
