imovie does not play clips from photos?

Thanks for looking into this. I tried your suggestion, but my 9.0.9 iMovie projects show up dimmed out when I try to update using 10.1.2. I tried to force it by doing an "open with iMovie 10.1.2" on the project, but got a message saying that "iMovie 10.1.2 cannot open this type of file " (extension is .rcproject). I also cannot import clips from 9.0.9 project. iMovie 10.1.2 tells me it cannot import the files (although they are all DV movies.

For some reason, the 9.0.9 project now appears as "project media" in 10.1.2, and plays properly on the timeline, showing all the stills - I have no idea how that happened. However, the old camera clips, stored as dv files, cannot be read into 10.1.2 ("iMovie cannot open files in the “DV movie” format); I tried to convert to .mov using QT, but get the same message. So now I have 2 questions:

1) How can I bring the DV clips into my 10.1.2 movie, so I can add them to the timeline?

2) How do I make the material edited on the 10.1.2 timeline into a project or movie?

Aaah! I think I found the problem: the clips did not have an extension (although they were recognized by the Mac OS as DV movies. When I renamed a clip by adding ".dv" to it, it snuggled nicely into my timeline!

Thanks so much - even if there was not information to find the solution, it helped a lot to have someone to keep urging me to go in the right direction.
