Re my last post I got confused by Apple's numbering system for iPhoto and iMovie (easy to do I guess). I have iPhoto 11 (which is also called 9) and iMovie 11. Still have same problem. Tried adding a new video to iPhoto to see if that triggered IMovie to recognise my recent iPhoto videos. For a time it seemed that it was registering them - quite a long pause while the blue line moved slowly across the download screen - but zilch showing up under iPhoto videos in bottom left box of iMovie screen. Can anyone help with a solution?
This works for me but I have an SSD and an internal HDD. My iPhoto Library is stored on the HDD via a symbolic link, but when I re-opened iPhoto in step 7, it gave me two libraries to choose from. One has the original file path:
(1) (Users/username/Pictures/iPhoto Library)
The other has the actual file path
(2) (Volumes/Macintosh HD/Media/Pictures/iPhoto Library)
.....but it's the same library.
However, if I chose option 1, it doesn't work. Option 2 does work, but iPhoto seems to take longer to open.
