Your disc and / or drive is dirty and / or defective.
I don't know what to tell you. I tried two different discs from two different Redbox machines (I said Netflix in my previous message). Neither one appeared scratched up and both of them are relatively new discs since the movie just came out to the Redbox machines in the past week or so. I used cleaner and wiped them off when the error initially showed up. I've used the same DVD reader very recently (before and between and after trying both the SNWH discs) for multiple other discs and haven't had problems. For them to both stop at exactly the same place seems unusual to say the least and suggests a software issue to me. Unless my reader is older and uniquely incapable of reading this particular disc.
