Thanks. We will definitely be rethinking our process to be safer with the clips in the future. After some research and testing we think we know what happened, just not why. Since the P2 cards and the P2-store use the FAT file system, larger clips have to be broken every 3.7 gigs or so, and when we transfered to the P2-store and then to the computer, one or two of those chunks must have been missing and the beginning chunk and end chunk were combined without the middle.
