Getting Access to Rendered transitions

Hello,

I have a simple sequence with desolves on each track (V1, A1-A16) that were rendered. I can see them with a call to GetSegmentsFromComposition() via Web Services.

However, when I try to get the file locators for the rendered disolve MXF files via GetFileDetails(), it fails. How do I get the file loctors for each rendered effect's MXF file?

Thanks,

Scott.
