This is usually a bad disc. [Oops, you said you didn't see any defects - not sure if the rest of this applies!] You probably can see scratches on the disc, or sometimes greasy fingerprints. I would recommend cleaning the disc, and trying again. For rental discs (I rent from the library, btw) I almost always clean them first. You can't believe how many greasy fingerprints get on there. They can affect playback as you describe. Sometimes you can hit Chapter+ to get past the "bad spot" and continue on, but this ruins the movie experience.
Anyway, this is not the players fault. I've tried discs that experience this behavior (I've only had a few) in my LG BH200, and they also get stuck at the exact same spot.
If the disc gets stuck at startup or in the menu, it might be BD Live related. Just remove the USB drive (if you have one inserted) to disable BD Live.
