My disc 3 is pretty scratched.... 2 clips are corrupted. Need someone to move on to the next save point for me.

I read through the forums and tried changing to low resolution movies, and it got me through the first clips. But, with no save points in between, the clip where it shows ragnarok is corrupted on low resolution.
So if i set it on low resolution movies, the first clip works, but the second doesn't. And if i set it on high resolution, i cant even get passed the first clip cause it crashes.

Edit: whoops.. forgot to put link heh..
