iMovie '09 not seeing iPhoto '11 videos???

Hello,

I recently upgrade to iPhoto '11, but kept iMovie '09.

Is iMovie '09 compatible with the new iPhoto? For accessing the iPhoto Videos, I mean?

I was certain that it worked on the first day, but it doesn't now.

Am I mistaken?

Perhaps I used it just before installing iPhoto '11.

I want to be sure before buying iMovie '11.

Cheers.
