Can preview but not import all P2 files

Creative Cow Crew,

Try this one on:

I was importing some P2 files into FCP 5 (most recent updates installed) from a lacie hard drive, and was able to preview all clips I wanted, but was repeatedly refused by FCP when I tried to import some of them.

All the files are complete, including Contents folder and Lastclip.txt. The odd thing is that all clips show up in the browser window, and ALL clips can be played in the preview window, with audio, no worries, but only SOME of the clips form that particular P2 card file will import into FCP and become proper Quicktimes.

I also copied the clips to my internal drive off the LaCie and tried to import them that way--no difference. Last, I even changed the capture scratch folder to make sure there wasn't a problem there. No dice still.

Anybody with an explanation? All clips were shot 24PN at 720P on an HVX200.

Thanks,

Burk
