....MGS4

So a couple weeks ago I posted asking if I should play through MGS4 because I'd played it here and there but didn't really care for it. Well I am happy to say that last night I finished and I really enjoyed it. Once I got used to the controls everything seemed to flow really good. As everyone stated the cutscenes were pretty ridiculous and long. But I think the gameplay and boss fights really evened it out.

On to a quick side note...... I left it paused mid final cut scene last night as it was putting me to sleep and I didn't want to miss the end. So before work today I finished the cut scene and iI was excited to play through again on a new save. However halfway through the unskippable final credits it froze. I popped out the disc and wiped it down and such to try again and once again it froze. Has anything similar happened to anyone else? Any suggestions on how to fix this?
