Taking the advice of several in this forum, I purchased a relatively inexpensive Canon ZR100 to use strictly as a playback machine for digitizing footage shot on my DVX100a. I'm using an iMac G5 with a 250GB G-Drive as a scratch disk, but I don't seem to be able to control the camera through FCP (i.e. can't rewind, play or fast forward). Any clues how to rectify this?
