Problem: If you are a very senior Senior, be careful of the pop-up enticements you do not understand. There is no way I can ever view the movie I have been wanting to see for a very long time. I now know that I have DVD and not Blu-Ray, whatever that is. Reaching anyone to question is a near impossibility in this sales-mad world. The saddest thing is that I have not found anyone in my area to whom I can just give this movie in exchange for an opportunity to view it. Disappointed Old Lady
Solution: Negative
