If your like me who still uses an Analog miniDV to capture videos on special events, since early 2008 the MacBook Pro now uses a Firewire 800 and went away with the Firewire 400. You would need special cable or adapter to get the job done.
The last MacBook Pro I used which was issued to me when I was working for the local government was an older model around (2007) not the new unibody. Port available to me back then was the Firewire 400. The cable I used was a 4pin to 6 pin to convert my analog miniDV to digital.
Here is my Sony HC 32 cradle for my analog miniDV where I hook up the 4 pin to the second slot marked DV.
So you can either get an adapter that converts Firewire 400 to Firewire 800.
Or get a 4pin to 9 pin Firewire cable.
I got the 4pin to 9pin cable which cost P900( around $21-$22) in a store I found in SM Megamall.
Now I started to convert all those analog miniDVs I have collected and planning to get a digital camcorder in the future or a point and shoot camera that shoots HD videos.
