I don’t understand. Please be more specific.

when trying to digitize footage under “log and capture” the screen says “preview disabled” across color bars, and won’t allow “capture now.” there’s no video entering the computer. the first time I tried, it worked; now it doesn’t. I’m running a MacBook Pro with 2 gigs of RAM; an external 320 hard drive. I have a Canon Optura20 connected via firewire direclty to the computer. the external hard drive is connected via firewire USB 2.0. I’ve tried two firewire cables. I’ve downloaded and re-installed quicktime. I’ve run disk utilities. I’m stumped. this is Final Cut 5.1.4
thanks for any help.
