FMLE not Recognising Firewire Device

Hi,

I am trying to get my Canon XH A1 to connect to the Flash Media Live Encoder usinig Firewire 800. When I launch FMLE, i get an error saying 'no video capture device detected. Please check if your video devices are connected properly and not used by another application'.

I have tested the firewire connection. Its working fine, i can see my camera output in various applcations that i've tested. Can anyone tell me if there is a setting somewhere that I need to set the capture feed to Firewire? I can't see anything in the help files.

Its a Mac with OSX 10.6.4 that i'm running.

Thanks,

Steven.
