I'm guessing you're using a firewire to capture to the computer.
Check for either a USB connection on your camera or even better, a SD card that you can remove from the camera and put into your computer. In either case, once you connect your camera to the computer as a 'hard drive' instead of as a camera, you should be able to access the avchd file in its native digital format. Copy it to your hard drive, disconnect the camera and open the file in your video editing software.
