Thanks Joe.
Yes, AVCHD (.mov) No, the hard drive has 4 TB available (external drive) Possible, SD card is failing.
Since you use the DVX200 –maybe you can answer, and maybe this is part of the problem, but I was shooting a number of different shots in a school classroom. Most captured fine (start/stop) but a few times I hit the record button, it started to record and then stopped. I got a warning message: “recording stopped” with a little hour glass animation. It did that for a few seconds before returning to normal.

I’ve been playing around with FCP more and noticed that with the clips that fail to show up properly in the clip viewer, when I try to import them directly from the SD card, in the import box, the clip has a strip of white across the bottom in the thumbnail. If I take the clips, copy them to another drive (preferably the one that the library, events and project are one) I can import them and that little white strip is gone. And that seems to work.
I can open those video clips directly from the SD card in both Quicktime and Photos on the iMac.
So the problem seems to be getting them directly from the SD card into FCPx. Oh, and if I right-click the package contents of the library, the imported video that doesn’t show thumbnails, is there and will play fine when you expand and play by hitting the space bar.
Sorry for the long analysis. ???
