Did you actually check this link to see if the "library titles" answer can be found there?
I can't find it myself -- I tried a few different ways of phrasing the question in the "Hi! How can we help you?" box, but didn't see anything useful.
That said, my guess for the answer is that "library titles" would be older movies, so movies that cost the full $5.99 should be the ones that are eligible.
Yeah, the link didn't work for me. I think DirecTV removed whatever it once directed to.
However, I sent an email to DirecTV, and I think we all assumed correctly (though they tried to tell me the buy 4 movies promotion has expired haha).
They told me library titles are 3D movies priced at only $4.99, standard def movies priced at only $2.99, and HD movies priced at only $3.99.
Therefore, when it's not full price, I guess it's a library title.
