Stars and problems

Hi. I just exported a number of files though C1's Output tool. The Canon .cr2 files were all rated 5 stars. When I go to the Output location the jpg files are all there and they're all fine, except that they are now all rated one star. I'd like to have the five star ratings survive and be attached to these jpgs, so that I know that these are the best from a shoot when I go back to this assignment in the distant future.

Any thoughts?
