Transformers 4k (2007) Disc or Drive Issue

[Discotech]

So, I got the Transformers: The Ultimate Five Movie Collection. All of the discs work great except for the original Transformers movie. When I insert the disc into my BP60NB10, it just keeps spinning up and down. No errors are thrown, but it won't read the disc and just keeps spinning up and winding down, over and over. I eventually hit the eject button to help reduce the chances of damaging the drive. Even though the disc looks fine, I tried to clean it and it still does the same thing. When I put the disc in my UB820, it works fine. My guess is that there is something about that particular disc that the BP60NB10 just doesn't like, but I thought I would ask here.

FYI, this drive is flashed and other discs work perfectly.

Any thoughts or ideas?
