VOD Free Movies have rent pop up

[Ergo61]

Sometimes when I choose a movie from the VOD free movie list, a pop up will appear stating "Rent HD Rent SD."  It does state "free" in both of these choices, but when I make a choice, say Rent HD, a VOD purchase confirmation pop up appears stating "You have indicated that you wish to order a VOD event. Is this correct?  Choose yes or no."   

My question is, are these movies free or not?

Although free, you’re still renting them. The cost you will be charged, is the one you see(in this case that cost is “free”).

Thanks! I was thinking it was probably free, but the word "purchase" in the VOD purchase confirmation pop up threw up a yellow flag for me...
