User blog:Dragonlord247/Oblivion disc randomly stops reading.

So I got Oblivion the other day for my 360 and it's great and I see why people say that it's supieor to Skyrim. But I've been having a problem. Depending on where I am (Example: I'll be walking towards one of the gates in Anvil) the game will just stop reading and if certain NPCs talk to me the game stops reading as well. I toke the disc out and looked on it to find a white haz on it's edge and some spots on the disc from the cleaner that was used on the disc by who ever last cleaned it. I was able to wipe off the haz but I'm unsure of what to do with the dried cleaner on the disc. Should I just scrath it off with my finger nail? Or use some cleaner that I've got for cleaning discs and hope that will make it work. What should I do?
