Have you tried using MovieImportSetSampleDuration()? Pass in a duration and a
timescale for the duration value.

MovieImportSetSampleDuration(movieImporter, 1, 24) for example gives you 24
fps. You can confirm this by calling DoUserDialog and checking out the value
of the popup menu.

Here's a link to the docs for this call:

Here's a link to the full data exchange docs:

Hope that helps.
