Can't you just create a new folder, then drag-and-drop from the camera's card? With USB, that is. You might need a card-reader, but I'm thinking the camera probably has a USB port (my Canon T2i does).
CBP3, I'm a PC guy, so I'm actually just guessing here, but if there's a prickly relationship between Canon and Mac, I'm thinking it might be the video format? I recommend that might be an area to look into. And if that's the case, then transcoding your footage might be the best solution (perhaps with cineform).
