Hi , i would like to assist here .
What version of imovie
are you using ? Use the about imove menu.
version from life 09 "version 8.05" has been tested to work with your Canon 330.
Please download and install the ImageBrowser Updater for Mac OS X 10.3
Version 6.1.3http://software.canon-europe.com/software/0031674_0010578.asp?model=The Cam must be in a "mode" to work with imovie , normally the play mode .
Set this "mode" on before you reboot to test using the Cams controls or menu options .
Are there other modes , on the camera , see the Camera guide to find out ?
imovie imports from most camcorders with Firewire capability with ease.
Note: If your compatible device has both a USB and FireWire port, you will only need to use the USB port to work with iMovie '09. ... from apple notes :
I would test both options , after a reboot connect the Cam via USB directly to the Mac , not via a hub or keyboard USB port . make sure the DVD player is not loaded, load imovie , test.
And for Firewire , connect via Firewire , reboot , make sure the DVD player is not loaded. run imovie , test .
Some DVD camcorders may start your DVD Player application. If this occurs, quit DVD Player.
-Possible work around:
If you have movies on the camera please copy them to the Mac HD for importing by hand in to the imovie application if possible , option maybe available in a "mode" .
or by placing the DVD in to the Mac DVD drive , if it is a mini DVD do not insert it in to a slot loading DVD / CD Mac.
If your camera movies are the wrong format to import into imovie please use ,
MPEG stream clip or a similar video converter to convert to DV format video .
Apple support notes for connecting Cams :-
It states "AVCHD DVD camcorders do not work with iMovie ",
this is conflicting info from other support notes,
i hope this is not the case with the Canon 330.http://support.apple.com/kb/TS1059#3
I hope this helps .
