no loop option with movie import

I am missing the loop option after importing video clip in inspector.I am using the latest unity 3.5.1f2 version. I used to be able to check an loop option in the video options in previous project using 3.4 version. I used the same mpeg video clip through a material applied to the plane polygon.

Is there a bug with this new version.Thanks.

I’m having the same issue after upgrading to version 3.5.3f3. Have you found a solution?
