IMovie 10.0.6 won't save my imported videos (from DV camcorder)

Question

I am using this version of iMovie for the first time (I finally gave in and let 9 go), so maybe I'm missing something.  I am trying to import some VHS tapes and I'm using a miniDV camcorder to convert to digital, something I've done a bunch in previous versions with no problems.  The camcorder is connected with firewire to my MacBook.  So in iMovie I click "Import".  Here I can see and hear the tape when it plays.  There is a message that says "Camera Not Controllable", which is expected.  I click the blue import button down in the corner and the message changes to "Recording" with a counter for the time.  All seems great.  When I'm done I click "Stop Import", then "Close" and I'm taken back to the main iMovie window with the events list.  But in the only event, where it should have been saving the video, there is nothing.  I've tried this a bunch of times and created a new iMovie library on an external drive but nothing works.  It never actually seems to save any video.
Am I doing something wrong?  This is really frustrating!
Thanks,
Sean

I have exact same problem.
iMovie 10.0.6 won't save my imported videos (from DV Digital Video Camera JVC GR-D290E).
I have iMac 27" (end 2012), OS X Yosemite (10.10.2).
I tried to reinstall the previous version of iMovie 9. But the OS can not do it.
Note: At the other my MacBook4.1 (OS 10.5.8, iMovie 8.0.6) same operations are functioning normally.
What to do?
