I had some problems with our new P2 stuff. I fugured out that the you need to copy the whole directory off the P2. It is a folder called "contents."
The folder can then be imported in FCP 5.2 (or something new 4.5 will not work) using the import Panasonic P2 tab in the file menu.
The folder must be called "contents" and nothing else. This obviously causes problems when you are copying off a P2 store and have 10 different contents folders.
The first time we shot I was copying straight to a hard drive and calling them contents1 etc. I found one workaround where I copied the numbered contents folder back to a P2 card, renamed it "contents" then imported it. Then I realized if I just renamed stuff right on the computer it worked too.
Sorry this is so long, but hopefully you can learn something from my "research."
I sure hope we get NATIVE mxf viewing in the next FCP cause right now the situation kinda sucks.
