Firestore Quicktimes Won't Play!

[brokencrayonsqp]

We shot a concert last night with 5 HVXs with the Firestore FS100 recording 720p24 and Quicktime PN. On one of the Firestores, when you plug it into the computer, it recognizes all the Quictimes, but when you try to open one it says "The movie could not be opened. The file is not a movie file." The very first clip worked, but none of the later ones played back. When I tried to play them back on the HVX, it only recoginzed about 12 clips (there are actually about 40) and it only played a few seconds of each one, and they all had really bad digital staticy-noise stuff. Anyone know what this is and how it could be solved?

Thanks!
