NR films

Hola Grupo,
I'm sure this is going to reveal my beginners status, but here it goes.  This is the first time that I've found a film listed on the Nuestros Ranchos website that has an ancestor of mine.  This particular film could solve my which of two Marcos Sepulbeda's is mine mystery.  It's an Atotonilco el Alto, Jalisco  film #222109, batch C603001.  My ancestor listed on the film is Petra Maria Sepulbeda  baptised 11/03/1735.  Parents listed are Marcos Sepulbeda and Ma Margarita Franco.  If the grandparents are listed, that would solve my long-lasting mystery.   
The question is:  does the listing of these films on the NR site mean that a member has these films and can do a look-up?  Thank you so much for your help in this matter.   Alice
