Just an update. After reading this thread, I kind of freaked out and contacted Universal to see if they would be willing to exchange the flippers for standard blu-rays since I had already opened them. They stated it is not their policy to exchange discs that are not defective.
I realized the logic in that statement and tried to watch the films. The first movie played fine. The second started to freeze and skip about 2 to 3 minutes into the film. The third film would not play at all in my PS3. I tried to return them to the store that I had bought them from, but since they did not have the exact same discs, their hands were tied. I reached out to Universal again explaining the situation, and thankfully they have agreed to exchange all of the discs for standard bluray discs.
VERY thankful to Universal.
Universal exchanged blu/DVD flippers for single-sided DVD for me. They actually called me after I mailed them, saying their people had no trouble playing them. I said I played them in 3 different players with no luck. They exchanged them.
I will never buy any title, ever again, that has flippers.
