I've just changed my FireWire cable. I used to be able to just plug it in and it would detect and it was fine for Windows Movie Maker. Now I plug in nothing happends. I even try the switch off pc and camera then put all on still no luck. I have a Dell computer. I'm more than sure the Firewire is not built in because I got 4 at the bottom back, looks like a card to me if it's 4 in a row at the back. I also got 1 in the front, thats the one i'm using but I tryed all 5. No luck. I read something about delete the BOIS cache if I have a Dell computer? I have no idea i've tryed everything I need to get this working for Christmas any ideas, whould be great thanks.
