She requires several attempts to get her tinder lit. Only a few will light. 
I took it from another standpoint.  As Mike from lifeview mentioned, this is a beginner video..  I think it proved that, though Gretchen is the resident expert, she was having a difficult time starting a fire with sparks.  I think it magnifies the importance of trying out your firestarters and making sure you know how it works and what to expect..  There is no magic pill!   I think somewhere in there, she mentioned that the lighter could run out of fluid or something.  I think she also mentioned the importance of carrying your own tinder, cause the real stuff can be hard to light with a spark.
As it goes, I think the video has it's place, and it has made my wife more aware.  Tools are great, but "It's too late to learn to swim when you start to drown.." <- Something I live by..  Anyone remember who sang that?  It was a song a couple of years back..
