I love P2 cards and cameras like the HVX-200. But here's a tip from Apple that has bitten me a few times and I never put the two together. Apparently when you have multiple P2 cards mounted at once the likelihood of Final Cut crashing is increased. Go figure. I wonder why Apple has chosen to just post a note about it rather than issue a patch for it.
On computers with Mac OS X 10.4, Final Cut Pro 6 may quit unexpectedly while you're using the Log and Transfer window to transfer media from Panasonic P2 cards. If you have multiple P2 volumes mounted simultaneously, the likelihood of this happening may increase.
So do this...
To work around this issue, have fewer P2 volumes mounted at a given time.
All the more reason to buy a few of these, I guess.
