Yep, I think you're a generation young of FCP
Have you downloaded/installed the P2 drivers on the Mac? How did you transfer the files to the Mac or are you trying to L&T direct from the camera? If the latter, you're using FW, not USB, right?
Is it
Your intention to edit on that computer? Or are you just trying to grab and convert the footage?
Sorry for the million questions, but there are about that many quirks in the chain that can be awry with the P2 conversion process, especially on older versions of FCP🙂
If you get the chance, stop by dvxuser.com for a lot more detail on P2 transfer and trouble shooting...or drop me a PM and I can trouble shoot with u tomorrow (Sunday).
I do use a PB for in field transfer and small edit jobs still...primarily because of the PCMICA slot specific to the P2 cards...
