Thanks for the note about formating Jeremy.
Have tried the above, but still no luck. When I open FCP it gives me a message that it is ‘unable to find external devices – Apple Firewire PAL’
I’m looking into upgrading QuickTime, one of the trouble shooting sites suggests that may be the problem – have downloaded version 7.2, but as I’m running system 10.4.6, I can’t install the new QT!
