That looks like it should work. Is your camera a Flip Mino HD?
Have you tried FILE/IMPORT/MOVIE and navigate to one of these files?
Found this for SD http://support.apple.com/kb/HT1989?viewlocale=en_US&locale=en_US
and this for HD http://support.apple.com/kb/HT3332
If that does not help, I suggest that you re-post your question with the words "How to Import Flip Mino HD" in the title and maybe someone who has this camera will see it.
