PX-755SA Won't read DVD movie

I’m having an odd issue with my new Plextor PX-755SA not reading a DVD. My other computers and standalone DVD player read it just fine. The movie is Aeon Flux - Special Collector’s Edition. I’ve flashed to the newest firmware (1.05) but that didn’t fix the problem. The LED on the front of the drive is flashing five times, which according to Plextor would indicate “Failure reading PMA, TOC or ATIP”. I’ve tried 5 other movies and they all read just fine in the drive.

Any ideas? It seems pretty odd that this one movie is having problems in just this drive. Is there any sort of protection on the disc that is preventing me from loading this disc? I’m just trying to watch the movie!
