Despicable Me (2010) Blu-ray 3D [Region Free]

[Jude72]

Upgraded my blu-ray copy to 3D in November but only just got around to watching this today in 3D.

It started playing just fine in 3D but at the scene where they go to steal the Shrink ray the first time, it freezes, stutters a bit very slowly and then eventually jumps several chapters ahead. It then plays fine again. Took the disc out and it wasn't scratched and didn't have any dirt on it. Put the disc back in and it did the exact same thing at the same point. I was playing it on our PS3 Slim which has the latest firmware on it. Has anyone else experienced this problem? I've read that some had issues getting the disc to read in 3D but nothing about it freezing mid way through.

As for the 3D, I thought it looked awesome but we had to turn down the setting a bit because it was giving me terrible eye strain and a headache. This is the first 3D movie I've watched on our system that's given me this problem.
