Freezing Problem

[THFMDA]

I have the Sony BDP-S350 hooked up to my 32 inch Samsung LCD HDTV. My blu ray player was working wonders the first couple of months, until I purchased Hancock. The movie would freeze from time to time and skip scenes. So I thought it was disc since my other movies weren't doing it. So I exchanged it for another and I had the same problem.

So then I watched Cloverfield and the same problem. But my other movies weren't doing it. I bought Eagle Eye it was unwatchable with how much it froze. I couldn't get past the main menu. So I realized there was an update for the player, so I updated it. After updating it Eagle Eye worked flawlessly and I was happy. So I recently purchased, Wanted, The Eye, and Punisher.

So I pop in The Eye and 3 mins in it freezes! Then skips 2 mins worth of movie time and works fine. Then an hour and half into it, it freezes again. What's the problem? It's not the discs, the player is updated. It doesn't do it to all movies. How do I fix this?
