Go here and try the Ulead Video Studio 6 it's new, if you have the Platinum it comes with Video studio 4.0 SE and you can upgrade for half the price. You can download the trial version for 30 days.
The new version supports everything the Pinnacle Studio 7 does.
I have Pinnacle Studio 7 and it works with my Sony camcorder through the creative firewire port.
Ulead here
Pinnacle here
Both are pretty good programs
Firewire net is for linking computers to another 1394 port for networking only.
You need a digital photo program for downloading video to your computer as the ones above.
After you install the programs just hook to the 1394 port, turn the camera on VCD and transfer the video into the program where you can edit crop or whatever you like.
The trial versions will not allow you to do this until you buy the program. Just take a look at both of them and decide wich one you want.
Get the right one for your camcorder AV or DV is usually the choice.
I like both programs, I'm buying the Ulead Video 6 myself as the version I have dosen't do what the new one does.
